Question

how do electrons moving in a material relate to the ability of a material become a magnet?

Answer 1

A material is made up of atoms and every atom contains electron. Which is rotating around the nucleus, and we know electron have a charge, and the moving charge creates the magnetic field. So every moving electron generates a microscopic magnetic field.

Hence every atoms have a magnetic property due to the moving electron in the nucleus. In most of the objects, equal number of electrons spins in the opposite direction. Which cancel out each other's magnetic field that is the main reason that we are saying that cloths, comb etc are a weekly magnetize material. But in the iron, nikil etc like object electrons spins in the same direction, So due to this property of the atoms, it makes it strongly magnetized material.
