Question

why is the core of electromagnet made of ferromagnetic material?

Answer 1

The intensity of magnetization is higher
than paramagnetic or diamagnetic
materials.

Most important ferromagnetic
materials possess the highest magnetic
permeability so that a low reluctance is
offered to the magnetic flux.

The Hysteresis loop for the ferromag-
netic materials is biggest referring to a
higher value of residual magnetism.

Answer 2

Explanation:

Answer: Ferromagnetic materials have high magnetic permeability compared to air. Ferromagnetic core increases self inductance of the loop proportional to their relative permeability. Due to this reason, core of an electromagnet is made of ferromagnetic material.
