Material used in making permanent magnets

Answer 1

Answer:

ferromagnetic

Explanation:

Usually ferromagnetic or ferrimagnetic materials are used for making permanent magnets these materials includes iron, nickel, cobalt and some rare earth metals.

The properties of magnetic materials can be derived from their hysteresis loop which is a curve obtained by applying an alternating magnetic field to the material under test and measuring its magnetization vs. the magnetic field.
