Magnetic flux density (area density of magnetic field lines emanating from a magnet): B.
CGS system: Gauss and SI system = Tesla ... Tesla = 10^4 GaussThis is called magnetic induction. This is used for calculations of effects of current on magnetism (induction) and vice versa.
========
Magnetic field field strength or Intensity = H .
CGS : Oersted and SI system = Amp/meter. Oersted = 250/pi Amp/m
This does not take into account the magnetizability (penetration) of the medium by a magnetic field. So Flux density is more relevant in our calculations. However, For Earth's magnetic field or bar magnets, H is used.
=============
B = μ * H
Here μ is the permeability of the medium (relative permeability * permeability of vacuum).
The relation between them is a constant μ.
