Electromagnetic (EM) forces play the major part in many modern technologies. Motors, magneto-hydro-dynamic (MHD) seals, electromagnetic pumps, levitators, electrical bearings, and springs are some of the modern technologies in which EM forces play a leading role. In some applications, EM forces can reach tremendous values. For example, thanks to a capability to develop incredibly large [...]

Magnetic flux concentrators (also called flux intensifiers, diverters, or flux controllers) are made from high permeability, low-power-loss materials. They are used in induction heat treating applications in a manner similar to that of magnetic cores in power transformers. Article concentrates on effect of magnetic flux concentrators on life of induction coils. Click here to read [...]
