	What is initial permeability?
	The initial permeability is the limiting value of the permeability at the point of the magnetization curve and is given by the following equation:

	What is core loss?
	Core loss denotes the loss by an electronicsal transformer, such as a switching power supply, under a magnetization condition featuring a high frequency and a large amplitude. Operating magnetic flux density is given by the following equation:

	What is curie temperature?
	It is the critical temperature level at which the ferromagnetic property of the material changes to paramagnetic.

	What is saturation coercivity?
	The value of magnetic field strength at which the flux density becomes zero when the magnetic field strength is reversed after having been in a state of effective saturation magnetic flux density.

	What is inductance factor; AL value?
	To make the calculation of the inductance of a coil easier, the inductance factor is known as the AL value. The inductance of the core is defined as:
