How do you make a motor with a magnet and copper wire?
Gently place the free end of the copper wire to the side of the magnet. The magnet and the screw should start to spin. When you place the copper wire to the side of the magnet, you complete the circuit between the battery terminals. The current flows from one end of the battery, down the screw, and into the magnet.
Can magnet and copper wire produce electricity?
Here’s how it works: A magnetic field pulls and pushes electrons in certain objects closer to them, making them move. If you move a magnet quickly through a coil of copper wire, the electrons will move – this produces electricity.
Why does the copper wire spin?
The interaction of the two magnetic fields generate what is known as the Lorentz force, which is simply the force you get when you bring the same magnetic poles of a magnet together. This means the Lorentz force will push the wire on one side and pull it on the other side, which is why your wire keeps spinning.
Can you make an engine with magnets?
The notion of a motor driven by permanent magnets alone is therefore feasible and cannot be dismissed as defying conservation of energy. A permanent magnet motor would not produce energy and would not be a perpetual motion machine.
How do you make a homopolar motor?
Easy DIY Homopolar Motor

Can a magnet damage a motor?
A motor has a closed magnetic path, so magnets on the outside won’t have any effect. And if it’s an AC motor they can’t possibly affect it.
Can you make the motor turn to the opposite direction if so how?
In order to reverse the direction of an AC motor, the magnetic fields must be altered to provoke movement in the opposite direction. This easy switching of wires works because the polarity of the magnetic field is reversed, thus reversing the motor.
Can you build an electric motor without magnets?
Can you make an electric motor without magnets? Induction motors contain no permanent magnetic materials, instead they operate by inducing electrical currents in conductors in the motor’s rotor; these currents in turn give rise to a magnetic field in the rotor and thus produce torque.
Can magnets power a light bulb?
Whenever you bring coils and magnets together (in the proper orientation and moving with respect to each other), magic happens. In this case, it is the Edisonian magic of lighting a light bulb. Turning the crank rotates a coil inside of the large U-shaped magnets.
