DEMAGNETIZING FIELD IN A LENGTH OF THE ELECTRICAL STEEL SAMPLE CLOSED YOKE AND MAGNETIZED IN A COIL
Journal Title: Proceedings of Electrotechnical Institute Prace Instytutu Elektrotechniki - Year 2012, Vol 59, Issue 258
Abstract
In this paper distribution of demagnetizing field of a rectangular sample made of an anisotropic silicon electrical steel was determined analytically. The measuring windings were wound on the sample, which was placed in an homogenous external magnetic field in a coil. The distribution of the magnetic induction was measured and based on it demagnetizing field distribution was calculated.
