Abstract

Three layer of M4 laminations with search coil wound around them were used to measure the magnetic flux density. When the samples were magnetised under controlled sinusoidal conditions, the magnetic flux density increased in the top and bottom laminations while it decreased in the middle due to less permeability of air gap. The results confirm that the normal flux density leaving from the middle lamination when approaching to the air gap is almost equal to the total extra flux joining to the top and bottom laminations.
