What’s the difference between B and H fields? Why are there two separate concepts?
In: Physics
You don’t explicitly mention it, but i think you’re talking about magnetic fields.
No physicist here, but i learned the basics of this this.
This is tough to ELI5, as it is even hard to get when you study it.
B is magnetic flux, where H is the field strength.
B = µ * H
(actaully its vector B = µ * vector H)
Where µ is the permeability of the material.
That means, a higher field strenght or a more permeable material – or both – cause more magnetic flux.
There are no two separate concepts, but one. B and H are just different things which are interconnected via the material constant.
