Question
The relative magnetic permeability of a magnetic material is 800. Identify the nature of magnetic material and state its two properties.
Advertisements
Solution
A magnetic material having relative permeability of 800 would be classified as a ferromagnet. A few examples of such materials include iron and nickel.
Its two properties are:
(1) All ferromagnetic materials become paramagnetic when heated to a temperature above the Curie temperature (Tc).
(2) These materials show a strong attraction towards magnetic fields and have a tendency to become magnets themselves.
