Question

(a) Name one device which works on the magnetic effect of current.
(b) Name one device which works on the phenomenon of electromagnetic induction.
(c) Which device converts electric energy into mechanical energy?
(d) Describe the principle of working of an electric motor.
​(e) Explain the principle of working of an electric generator.

Answer 1

Electric Motor Produces Mechanical Energy

Explanation:

a.) Electric Motor works on the magnetic effect of current.

b.) Electrical Transformer works on the phenomenon of Electromagnetic induction.

c.) Electric Motor - electrical to mechanical energy.

d.) Principle of Electric Motor - In a magnetic field a rectangular shaped coil is placed and current is passed through it. So, It rotates because of force acting on it continuously.

e.) Electrical Transformer works on the phenomenon of Electromagnetic induction thereby converting mechanical to electrical energy. It has a pair of permanent magnet poles, which are having a rectangular coil, which is rotating in order to give the desired effects.
