Magnets have uses beyond being interesting toys and sticking things on metal, and one of the most widespread uses of magnets in industry is in electric motors. In electric motors, the magnet is used to generate rotation using electrical current passing through loops of wire.
Do electric motors have magnets in them?
Electric motors and magnets
Magnets are a primary component in electric motors. In order to work they need to be made of a coil of wire that can spin and is encircled by strong magnets. … The same concept occurs in motors, but they are modeled in a way that the repulsion is used to control an energy source.
Will motors work 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.
What is the price of electric motor?

Does Tesla use permanent magnet motors?
Recent dual motor Tesla models use a combination of a permanent magnet motor at the back and traditional induction motor at the front. Permanent magnet motors are more efficient than induction motor or motors with field windings for certain high-efficiency applications such as electric vehicles.
Why magnets are not free energy?
Why can’t magnetism be used as a source of energy? Because magnets do not contain energy — but they can help control it… … “As these charged particles move past magnets inside the turbines, they create a field around them that affects other charged particles,” says Cohen-Tanugi.
