Life is motion. Cars, ships, planes - everything moves. Every person knows what unites all moving devices created by man - this is an engine (motor). Making a real engine is a complicated process, but you can make a small motor yourself.
Necessary
- - Enamelled copper wire. Select the wire experimentally so that the coil does not bend during rotation.
- - Pins 2 pcs (non-enameled). The pins must be made of conductive materials.
- - Insulating tape;
- - Magnet (composition: rare earth metal and cobalt. Has a metallic luster);
- - Battery (D format).
Instructions
Step 1
The hardest part in creating this simplest mechanism is making a reel. To do this, take a wire and wind it around the battery so that the turns form a tight ring. You need to make about 40-50 turns. Next, carefully remove the copper ring from the battery. Wrap the end and the beginning of the coil (5-6 cm) around the ring (this is needed to secure the turns of the coil) and spread 180 degrees to the sides. Then sand the “legs” of the coil with sandpaper in order to remove the enamel.
Step 2
Take a piece of electrical tape, safety pins, and a battery. Secure the pins with electrical tape to the plus (+) and minus (-) of the battery (on one side at an angle of 90 degrees to the battery axis).
Step 3
Insert the stripped “legs” of the coil into the “ears” of the pins so that it rotates freely in this stand, but does not dangle much in it.
