Question

– What makes a material magnetic (i.e. what gives it its magnetic domains?)

In: 2

Answer 1

An atom has a nucleus full of protons and neutrons, and a “cloud” of electrons floating around it.

All moving electrons create a magnetic field, but in almost all atoms the electrons are not arranged correctly and so the fields cancel each other out.

A magnetic material has a “free pair” of electrons which **can** be arranged in the necessary way.
