Neutral Point | Magnetic Flux Density | Magnetic Potential

Neutral Point

This is a point at which the resultant magnetic flux densityDensity is the measurement of how tightly a material is packed together i.e. how closely the particles are packed in the material. The tighter the material is packed the more its... More is zero.

Magnetic Flux Density

This is the ratio of the magnetic field lines or flux φ to the cross sectional area (A) 

Magnetic flux density φ = \( \frac{Magnetic \; flux}{area} \scriptsize = (r) \)

The unit of magnetic flux density is weber (Wb)

Magnetic Potential

This is a measure of the workdone in moving a north pole from infinity to that point under consideration.
