What is the formula for magnetization in statistics?
This may be shown as M = Nm/V where M is the magnetization, N is the quantity of the magnetic moment, m is its direction and V is the volume of the sample. Calculate the magnetism in terms of the magnetic fields.What is the formula for magnetization per unit volume?
For the susceptibility ?, the definition is M =?H, where M is the magnetization (magnetic moment per unit of volume) and H is the magnetic field strength. This ? is dimensionless, but is expressed as emu/cm3.What is the formula for the magnetic moment?
?=p×B. The SI unit for magnetic moment is clearly N m T?1. ?=IA×B.- The curie law states that in a paramagnetic material, the material's magnetization is directly proportional to an applied magnetic field. But the case is not the same when the material is heated. When it is heated, the relation is reversed i.e. the magnetization becomes inversely proportional to temperature. ? = C/T.
