Magnetic Shielding Analysis

	83 - Magnetic Shielding Analysis of an Induction Furnace	Module:FQ	2011-01-17
	An induction furnace is an electrical furnace in which the current is generated within the metal by induction heating and the heat generated by the electric resistance melts the metal. The magnetic iron cores around the coil are used to protect the coil from being damaged. The magnetic iron cores also prevent the flux leakage so that the steel sheet outside the iron cores will not be heated. This note presents the used of magnetic field analysis to evaluate the flux leakage from the magnetic flux density distribution of an induction furnace with and without the iron cores.

	53 - Magnetic Shielding Analysis of a Shield Room	Module:FQ	2011-07-12
	A shield room is designed to protect equipment, such as precision equipment, from external magnetic field by the use of magnetic shielding. In JMAG, external magnetic field can be specified by the external field condition, so magnetic flux density distributions both inside and outside the shield room can be obtained. This example presents the use of magnetic field analysis to evaluate the effect of magnetic shielding of a shielded room.
