Numerous videos demonstrating the operation of an eternal flashlight on magnets roam the Internet. Most of the schemes are very simple, but in fact they are fakes. This article talks about schemes that really work. The first model was invented in the last century, then printed in a Soviet magazine. The second scheme is suitable for repairing a garden lamp. This model can be useful in the country. If you want to assemble a functional flashlight, be sure to read this article.

simple circuits

The first model is very easy to assemble. For its installation does not require special tools and extensive knowledge. The model works as a demo and is not suitable for home needs.

Materials and tools needed

For its manufacture you will need:

  • four round ferrite magnets (two large and two smaller);
  • square lantern stand (plastic board or piece of plywood);
  • a compact 5-10 volt motor (it can be removed from an old printer);
  • a small LED from a flashlight that does not work;
  • tool (glue gun, knife).

How to DIY

Assemble a simple flashlight according to the scheme:

  1. Glue the motor to the center of the bracket, fix it well so that it does not fall during operation.
  2. Place large magnets on both sides. They must be installed on edge, using brackets, cardboard and plugs so that they do not roll. The magnets must be symmetrical to the motor.
  3. Place the LED on a bracket in front of the motor, connect the wires.
  4. The small magnets should be above the motor. For them, you need to make a stand from improvised materials (for example, from cardboard). Cut out the stand, make a hole in the middle, insert a rod into it and put it on the motor shaft. Put small magnets on the stand and glue them with glue.

As soon as all the magnets snap into place, the flashlight will start to glow.

Many craftsmen disassemble old rechargeable flashlights, remove parts and make eternal flashlights that work without batteries in a magnetic field from three magnets. These flashlights need to be shaken to recharge.

Materials and tools needed

To make a portable garden lantern, you will need:

  • old plastic case;
  • LED removed from this lamp;
  • 3 piece magnets;
  • copper wire for winding;
  • plastic bottle for making the generator.

How to DIY

For the manufacture of the second model, special knowledge is required. If you are not afraid of difficulties, proceed with the assembly according to the scheme:

  1. Place three magnets in the vial – two around the edges and one should hang down the middle.
  2. Attach the outer magnets securely (they can be glued with superglue).
  3. Wind a copper wire around the vial of an impromptu generator. It is necessary to make three windings like a coil of 600-700 turns in front of each magnet. All windings must have their own rectifier, which are connected in parallel. Rectifiers should have only one output.
  4. An LED is attached to the wires.
  5. Insert the structure into the case, fasten it securely.

If such a flashlight is shaken for 1-2 minutes, it will charge and the LED will start to glow.

The power of the flashlight depends on the power of the bulb, the duration of work depends on the ability to wind the coils, as well as on the quality of the magnets. If you have a broken rechargeable flashlight at hand, you can turn it into such an unusual device.

Magnetic motors do exist. They can be used to illuminate small spaces or to demonstrate experiments to children.
