Question

How does an electric motor convert electrical energy into mechanical energy?

Answer 1

When current flows through the motor, it powers electromagnets that are attracted and repelled by the poles of permanent magnets in the motor. The movement of the electromagnets turns a rod in the motor, which makes the mechanical energy available.

Answer 3

yep! option A looks correct

Answer 4

thx! :)

Answer 5

np !

Answer 6

coils of electrical motor experience torque under magnetic field.This torque is equal to cross product of magnetic moment of coil and magnetic field inside the motor due to cylindrical magnet.
it will rotate at the cost of applied current and will stop if supply is stopped.
