b) Iron
c) Nickel
d) Cobalt

Answered by admin @ 16/08/2021

answer : option (b) Iron

explanation : electromagnet is a type of magnet in which magnetic field is produced by passing electric current through it. if electric current is turned off, magnetic field disappears.

usually, electromagnet consists wire wound into a coil. The wire turns are often wound around a magnetic core which is made from $\textbf{ferromagnetic}$ material.

and we know, iron is a ferromagnetic material. so, it is commonly used for making an electromagnet.
