quantitykind:MagneticFluxDensity
"Magnetic Flux Density" is a vector quantity and is the magnetic flux per unit area of a magnetic field at right angles to the magnetic force. It can be defined in terms of the effects the field has, for example by \(B = F/q v \sin \theta\), where \(F\) is the force a moving charge \(q\) would experience if it was travelling at a velocity \(v\) in a direction making an angle θ with that of the field. The magnetic field strength is also a vector quantity and is related to \(B\) by: \(H = B/\mu\), where \(\mu\) is the permeability of the medium.
