Magnetic field, field strength, and flux density - EMFs.info

Sometimes, people will be very precise and talk about either the magnetic flux density or the magnetic field strength. But actually "magnetic field" is perfectly valid as a description of either - both the magnetic flux density and the magnetic field strength are examples of a magnetic field.

What is magnetic field strength? - Definition from WhatIs.com

Magnetic field strength is one of two ways that the intensity of a magnetic field can be expressed. Technically, a distinction is made between magnetic field strength H, measured in amperes per meter (A/m), and magnetic flux density B, measured in Newton-meters per ampere (Nm/A), also called teslas (T).

Magnetic properties of materials - University of Surrey

In ferromagnetic materials the hysteresis phenomenon means that if the field strength is increasing then the flux density is less than when the field strength is decreasing. This means that the permeability must also be lower during 'charge up' than it is during 'relaxation', even for the same value of H.

So for ferromagnetic materials the ratio of flux density to field strength ( B/H ) is not constant but varies with flux density. However, for air cored coils or any non-magnetic medium core such as woods or plastics, this ratio can be considered as a constant and this constant is known as μ o, the permeability of free space, ( μ o = 4.π.10-7 H/m ).
