چکیده:

This paper presents experimental evidence that four types of magnetic laminated core materials of grain oriented 3%silicon-iron cut and magnetized at 0o to their rolling direction and one type of amorphousmaterial (POWERCORE)ffects the magnitude of the normal flux density distribution transfer between them. Stacks of laminations wereagnetized at 50Hz between 1.0 and 1.8 T and the normal flux was found to vary from about 0.5 to 1.2 mT. The fluxtransfer in any group of samples could vary by as much as 100% according to the different types of materials used with
.possible consequential differences in the power loss due to associated inplane eddy currents.
