Question

(a) If the number of turns of wire on the electromagnet is increased,
what effect will it have on its magnetic strength?
(1) Why is soft iron used in an electromagnet?​

Answer 1

Answer:

a)The magnetic field strength of an electromagnet is therefore determined by the ampere turns of the coil with the more turns of wire in the coil the greater will be the strength of the magnetic field.

b)Electromagnets are made of soft iron because soft iron has low retentivity and low coercive force or low coercivity. Soft iron is a soft magnetic material.
