Question

If all atoms have electrons that are in motion about an atom, why aren't all materials magnetic? 1. the net magnetic field created by ordinary materials is zero. 2. ordinary materials do not create magnetic fields. 3. random motion of electrons does not create magnetic fields.

Answer 1

The answer would be the first option. This occurs because of the presence of the protons. The positive charge of protons and the negative charge of electrons set the balance of each other and usually the net charge turn out to be zero.
