Question

What is the property of permeability in magnetic materials?

(a) how easily the magnetic flux is broken/clear

(b) how easily the magnetic flux is set up

(c) how long the magnetic flux takes to form

(d) how long the magnetic flux takes to clear

This question was posed to me during an interview.

I'd like to ask this question from Magnetic Materials topic in division Electrical Engineering Materials of Design of Electrical Machines

Answer 1

Correct option is (b) how easily the magnetic flux is set up

To explain I would say: The basic operation of magnetic material is to form magnetic flux. Permeability is the ability of the material to determine how easily the magnetic flux is set up.
