How to make a simple motor

You probably should remember from school physics that a magnetic field on a current-carrying conductor the force, leading it in rotation. In our simple engine, the Assembly instructions which is given below, the rotor is a screw. It will carry a constant electric current and magnetic field, respectively, will provide a magnet. It's very simple. A simple engine can collect even a child, spending not more than half a minute.

You will need

• battery, wire, screw, magnet

Instruction

1. Take a piece of wire, strip both ends. Slightly bend it and set briefly aside.
2. Take the screw and place it on magnet hat down (it should stick flat side). The magnet Assembly of the electric motor can be removed from the old headphones little, "bumps" or remove the compact version of the fridge magnet. A screw with a magnet to the edge of the battery. The screw is magnetized and will stick with the edge. The rotor of the motor ready.
3. A finger of one hand squeeze one of the ends of the wires to the opposite screws from the edge of the battery. The second end near to the other edge, the cap screw with a magnet. By contact of the screw begin to come into motion.
