True or False questions: ( ) Keeping a coil to rotate at constant angular speed

Question

True or False questions:

(                 ) Keeping a coil to rotate at constant angular speed inside a constant B field can generate AC current, which varies sinusoidal with time. This is a generator.

(                 ) Keeping a coil to rotate at constant angular speed inside a constant B field can generate AC current, which varies sinusoidal with time. This is a motor.

(                 ) Current carrying coil can experience torque hence rotate inside a B field; this is a generator, which converts mechanical energy into electrical energy.

(                 ) Current carrying coil can experience torque hence rotate inside a B field; this is a motor, which converts electrical energy into mechanical energy.  

Explanation / Answer

a) true, when we rotate a coil in uniform magnetic field at any angular velocity then an Emf generated on the coil which is responsible to induced current.

B) false, motor can't generate current.

C) true. Generator converts mechanical energy to electrical energy.

D) true, motor converts electrical energy to mechanical.
