And today we’ll talk about how to make an engine from a battery, copper wire and a magnet. Such a mini electric motor can be used as a fake on the table of a home electrician. It's quite easy to assemble, so if you're interested this type classes, then we will provide detailed instructions with photos and video examples, so that assembling a simple motor is understandable and accessible to everyone!

Step 1 – Prepare materials

To make the simplest magnetic engine with your own hands, you will need the following materials:

Having prepared everything necessary materials You can proceed to assembling a perpetual electric motor. Making a small electric motor at home is not difficult, as you will now see!

Step 2 – Assembling the homemade product

So, to make the instructions clear to you, it’s better to look at it step by step with pictures that will help you visually understand the principle of operation of a mini electric motor.

We immediately draw your attention to the fact that you can invent the design of a homemade small engine in your own way. For example, below we will provide you with several video lessons that may help you make your own version of the engine from a battery, copper wire and a magnet.

What to do if the homemade product does not work?

If suddenly you have assembled a perpetual electric motor with your own hands, but it does not rotate, do not rush to get upset. Most often, the reason for the motor not rotating is too long distance between the magnet and the coil. In this case, you just need to trim the legs a little yourself, on which the rotating part rests.

That's the whole technology for assembling a homemade magnetic electric motor at home. If you watched the video tutorials, you are probably convinced that you can make a motor from a battery, copper wire and a magnet with your own hands. different ways. We hope that the instructions were interesting and useful for you!

It will be useful to know:

Making an electric motor from what you have at hand is not at all difficult.

I came across the idea for such a motor on the website www.crafters.ucoz.ru As you can see in the photo above, for the motor we will need adhesive tape, a couple of pins, a magnet, a battery and a piece of copper wire.

Instead of a regular battery, it is better to take a battery because the battery charge for such an electric motor will not last long. Take copper wire and wind 30-50 turns around the battery.

Secure the ends of the wire to the opposite edges of the resulting rotor; they will serve as the axis. They can be tied in a knot.

Clean both ends of the wire from the varnish insulation with sandpaper or a knife.

Now take a battery, tape and pins, attach the pins with tape to the battery contacts, insert the prepared copper rotor into the ears of the pins.

ATTENTION! At this moment, the circuit of our rotor closes the battery contacts and it is not recommended to keep this structure in a “quiet” position for a long time! The battery electrolyte can become very hot, so do not make the rotor less than 30 turns than more topics better (more resistance). Now place a magnet under the rotor on the battery, it will “stick” to the battery itself. The rotor will begin to rotate quickly.

The rotor should not touch the magnet and it would be even better if the magnet is at a distance of 5-10 mm from the rotor. Try the magnet in different positions, rotate it, try to move it away from the copper rotor, achieve maximum speed rotation.

This simplest example electric motor, we went through its circuit more than once in physics lessons at school, but for some reason we were never shown this simple and interesting design :) Let's watch a video of how this homemade motor works.

What do you do when the power goes out at night? Most likely, you light candles and spend the evening waiting for the electricity to come on. And you can spend this time usefully. For example, illuminate a room using a regular magnet and wire, which will allow the lamp to operate without electricity. Or make a motor that can work autonomously.

DIY electromagnetic motor

The homemade electric motor easy to make from scrap materials at home. It is worth noting that such a device can be used not only as a visual example, but also for its intended purpose, for example, by attaching a fan to the rotor.

To make it you will need:

• Spoke;
• Thin metal plates;
• Bolts with nuts;
• Copper wire;
• A piece of plywood.

From metal sheet 0.2 mm thick, cut out 5 rectangular plates 40 by 15 mm. We make holes in the center of all plates and put them on the prepared knitting needle. Next, you need to secure the plates together with electrical tape.

For better rotor rotation, the ends of the spokes are sharpened, thereby ensuring minimal contact with the surface.

Then, on the axis you need to attach a homemade current breaker, which is made of the metal from which the plates are made. The breaker dimensions are 3 by 1 cm. This plate is folded in half and placed on the axle.

Next, we make the base from plywood. To do this, drill three holes on a piece of plywood measuring 50 by 50 mm (two for bolts along the edges and one in the center for installing the rotor). We make a U-shaped holder for the upper part of the rotor from a metal plate. And drill a hole in it in the center.

After this, to make the stator, we cut out three plates from metal that will connect the bolts in the lower part of the structure and make two holes for the bolts in them. We put these plates on the bolts, and insert the boots into the holes on the wooden platform.

Next, the bolts are wrapped with electrical tape, and 500 turns of copper wire is wound onto it. A holder for a contact breaker is attached to one of the corners of the wooden structure. Electricity of 12 Volts is connected to the coils.

How to make a motor from a battery correctly

This electric motor is rather of a demonstration nature. In order to make the simplest motor It will take some time and available materials.

Essential elements:

• Battery 1.5 V;
• Small magnet;
• Pins;
• Scotch;
• Plasticine.

First of all, it is necessary to make a coil, which will act as a rotor. To do this, we wind enameled copper wire around the battery (6 turns). We thread the ends of the wire into the resulting coil and secure it with knots.

To add rigidity to the structure, it is better to use wire with a cross-section of at least 0.5 mm.

We bite off the ends of the coil with pliers (they should be about 4 cm long). We completely clean one end of the varnish, and the other only on one side (it will act as a breaker).

Next, using tape, attach the pins to the battery contacts. To do this, you just need to attach pins and wrap the battery with tape. Then, a magnet is installed on the battery using plasticine.

We insert the coil into the ears of the pins. A magnetic field is generated in this coil, due to which the movable structural element rotates. If rotation does not occur, swap the coil contacts.

Speaker magnet, copper wire and lamp for making a lamp

The most in a simple way To bring a fluorescent lamp into working condition is to place it in the electromagnetic field of an ordinary magnet, which is used to work in old Soviet speakers.

The device consists of:

• Round magnet;
• Copper wire.

To make this device, you first need to remove the magnet from the speaker. Next, using a hammer without using great strength With light blows, knock the metal plates off the magnet.

Note! If the plates do not move away from the magnet, you can soak it in solvent for a while.

After the plates are removed from the magnet, it is necessary to clean it of dirt. To do this, use a regular rag or rag.

Next, the winding is manufactured. To do this, take a piece of copper wire insulated. The wire should be long enough to fold it in half and wrap the magnet with five turns. The double end of the wire is threaded into the resulting wire eye.

After the magnet is wrapped, a regular Fluorescent Lamp. This design can be equipped decorative materials and use as a stand-alone lamp.

The best homemade magnets

The use of magnets in everyday life is so widespread that listing them all would take a lot of time. But since many are rather entertaining, we will dwell in more detail on listing the widely used ones.

Magnets use:

• During installation work;
• Window cleaning;
• As holders.

First of all, it is worth noting that the search for magnets is not very difficult task. Magnets small sizes, you can find in old headphones. More powerful neodymium magnets can be removed from old computer hard drives.

Let's assume you are working with wooden structure. In one hand you hold a hammer, and in the other an element of this design. In this case, holding an armful of nails is not entirely convenient. To do this, you just need to place a magnet in your chest pocket and glue nails to it.

There are situations when you have to tighten screws in hard-to-reach places where it is not possible to hold the screw. To do this, simply attach a magnet to the metal part of the screwdriver. A magnetized screwdriver allows the bolt or screw to hold on its own.

If you glue small magnets to computer desk(in any convenient location), then you can use them as holders for various USB or other types of wires. To do this, small springs are placed on the wires (springs from handles can be used), which are a metal magnetized structure.

The attractive force of a magnet depends not only on its size, but also on the time of its operation.

As a component of decor, magnets can be used as fastening elements for a puzzle located on the refrigerator door. To do this, take any photograph that is outlined into certain elements. To each element using regular glue a small magnet is glued. The photo is divided into its component elements. After this, it is assembled on the refrigerator door in the form of a puzzle.

What can be made from a battery (video)

In order to assemble an almost eternal electric motor at home, all you need is ingenuity and ordinary knowledge in the field of electrical engineering. Which will undoubtedly come in handy in some cases.

How to make an electric motor in 15 minutes

• DIY or Do It Yourself

It is always interesting to observe changing phenomena, especially if you yourself participate in the creation of these phenomena. Now we will assemble a simple (but actually working) electric motor, consisting of a power source, a magnet and a small coil of wire, which we will make ourselves.

There is a secret that will make this set of items become an electric motor; a secret that is both clever and amazingly simple. Here's what we need:

1.5V battery or accumulator.

Holder with contacts for battery.

Magnet.

1 meter of wire with enamel insulation (diameter 0.8-1 mm).

0.3 meters of bare wire (diameter 0.8-1 mm).

We'll start by winding the coil, the part of the motor that will rotate. To make the coil sufficiently smooth and round, we wind it on a suitable cylindrical frame, for example, on an AA battery.

Leaving 5 cm of wire free at each end, we wind 15-20 turns on a cylindrical frame.

Do not try to wind the reel particularly tightly and evenly; a slight degree of freedom will help the reel better retain its shape.

Now carefully remove the coil from the frame, trying to maintain the resulting shape.

Then wrap the loose ends of the wire around the coils several times to maintain the shape, making sure that the new fastening coils are exactly opposite each other.

The coil should look like this:


Now is the time for the secret, the feature that will make the engine work. This is a secret because it is a subtle and non-obvious technique and is very difficult to detect when the motor is running. Even people who know a lot about how engines work can be surprised by a motor's ability to perform until they discover this subtlety.

Holding the spool upright, place one of the free ends of the spool on the edge of the table. With a sharp knife remove the top half of the insulation, leaving bottom half in enamel insulation.

Do the same with the other end of the coil, making sure that the bare ends of the wire are facing up at the two free ends of the coil.

What is the point of this technique? The coil will rest on two holders made of bare wire. These holders will be attached to different ends of the battery so that electricity could pass from one holder through the coil to another holder. But this will only happen when the bare halves of the wire are lowered down, touching the holders.

Now you need to make a support for the coil. They are simply coils of wire that support the coil and allow it to rotate. They are made of bare wire, since in addition to supporting the coil, they must deliver electric current to it.

Simply wrap each piece of bare wire around a small nail and you have your desired motor part.

The base of our first electric motor will be the battery holder. This will be a suitable base because with the battery installed it will be heavy enough to keep the electric motor from shaking.

Assemble the five pieces together as shown in the picture (without the magnet first). Place a magnet on top of the battery and gently push the coil...


If everything is done correctly, the REEL WILL START ROTATING FAST! We hope that for you, as in our experiment, everything will work the first time.

If the engine still does not work, check everything carefully electrical connections. Does the reel rotate freely? Is the magnet close enough (if not, install additional magnets or trim wire holders)?

When the motor starts, the only thing you need to pay attention to is that the battery does not overheat, since the current is quite high. Simply remove the coil and the chain will be broken.
Let's find out exactly how our simplest electric motor. When electric current flows through the wire of any coil, the coil becomes an electromagnet. An electromagnet acts like a regular magnet. It has a north and south pole and can attract and repel other magnets.

Our coil becomes an electromagnet when the bare half of the coil's protruding wire touches the bare holder. At this moment, current begins to flow through the coil, a north pole appears at the coil, which is attracted to the south pole permanent magnet, and the south pole, which is repelled by the south pole of the permanent magnet.

We stripped the insulation from the top of the wire while the coil was standing vertically, so the poles of the electromagnet will point to the right and left. This means that the poles will begin to move to be located in the same plane with the poles of the lying magnet, directed up and down. Therefore the coil will turn towards the magnet. But in this case, the insulated part of the coil wire will touch the holder, the current will be interrupted, and the coil will no longer be an electromagnet. It will rotate further by inertia, touch the non-insulated part of the holder again, and the process will repeat again and again until the current runs out in the batteries.

How can you make an electric motor spin faster?

One way is to add another magnet on top.

Apply a magnet while the coil is spinning, and one of two things will happen: either the motor will stop, or it will start spinning faster. The choice of one of the two options will depend on which pole of the new magnet will be directed towards the coil. Just remember to hold the bottom magnet, otherwise the magnets will jump towards each other and destroy the fragile structure!

Another way is to place small glass beads on the coil axis, which will reduce the friction of the coil on the holders and also better balance the electric motor.

There are many more ways to improve this simple design, but we have achieved the main goal - you have assembled and fully understood how a simple electric motor works.
