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 and Magnetic Flux Density:

Magnetic flux is the number of field lines passing through a surface placed in a magnetic field.

Magnetic flux density is the ratio of the magnetic field lines or flux φ to the cross-sectional area (A) of a given surface at right angles to the magnetic field.

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

The unit of magnetic flux density is Weber (Wb)

Magnetic Potential:

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