Question

Which properties make materials suitable for use as a core in an electromagnet?

Answer 1

Core of electromagnets are made of ferromagnetic materials which have high permeability and low retentivity. Soft iron is an example. Electromagnets are used in electric bells,loud speakers and tekephone diaphragms. Giant electromagnets are used in cranes to lift machinery and bulk quantities of iron and steel.
