I didn’t know there was more than 1. OK , this lack of knowledge must be rectified. Can someone suggest reading material for those of us without doctorates that can explain this please.

I’d just get a used electromagnetism textbook that’s only a few years old. However, that’s going to assume you already have a pretty solid base understanding of physics, you can’t really just jump straight to electromagnetism. You could try, but it’s likely gonna be like reading a different language. Maybe look into glasses at a local community college?

Imagine a material made of groups of atoms, each group having an arrow. Ferromagnetism: If the material is in magnetic field, all arrows point along the magnetic field. Anti-ferromagnetism: If the material is in magnetic field, all arrows point against the magnetic Alter-ferromagnetism: If the material is in magnetic field, some arrow point along the external magnetic field and some arrows point against the external magnetic field.
