What is Susceptibility ?

What is Magnetic susceptibility?? Susceptibility is  measure of how much a material will become magnetized in an applied magnetic field. Whenever matter interacts with magnetic field, an internal magnetization or polarization ( J  ) is created which  either opposes or augments the external field.  If the polarization opposes the applied field,then the effective field within… Read More »

What is permeability?

what is permeability ?Permeability which is also called magnetic permeability, is defined as it is a constant of proportionality that exists between magnetic field  intensity and  magnetic induction This constant is approximately equal to  1.257 x 10-6 Henry per meter (H/m) in free space (a vacuum). In other materials it is much  different, often substantially greater… Read More »
