# flux density and field strength: ##### Magnetic field, field strength, and flux density

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. And just using "magnetic field" is a lot simpler ... ##### Magnetic field intensity (H) flux density (B) THE JARGON

Usually, magnetic field strength is defined by the unit of Oe･A/m ( Oersted・Ampere/meter ). And when it is defined by flux density, the units of G (Gauss) or T (Tesla) are used. This means that flux density B is a value which includes magnetizability and magnetic flux H does not include magnetizability. ##### Flux and flux density - schoolphysics ::Welcome::

Flux and flux density. To understand the meaning of magnetic flux (Φ) and magnetic flux density (B) think first about an ordinary bar magnet. Around the magnet there is a magnetic field and this gives a ‘flow of magnetic energy’ around the magnet. It is this flow of energy that we call magnetic flux (Φ).We think of magnetic flux as flowing from the north pole of a magnet round to its ... ##### What is the difference between magnetic field strength (H ...

Answer (1 of 3): H is typically referring to the field generated by an electromagnet used to magnetize a permanent magnet.

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 ). ##### Magnetic Field Strength Formula - Definition, Equations ...
