What is the difference between B and H?

[Heisenberg7]

A week ago, I started studying electromagnetism. I was introduced to a few new concepts and one of them was H. Now, in my book, they defined H as just magnetic field strength and B as magnetic induction. The thing is, I don't understand what those terms really are (in a physical way), let alone the difference between them. I know how they are connected and I've read at least a dozen definitions and watched a few videos but they always somehow manage to go past the explanation.

Welcome to PF.

You will get other better answers, but for me the easiest way to think about it is in terms of the magnetic permeability $\mu$
