Answer» something different Eddy current loss is less so you save the energy Amagnetic coreis a piece ofmagnetic materialwith a highmagnetic permeabilityused to confine and guidemagnetic fieldsin electrical,electromechanicaland magnetic devices such aselectromagnets,transformers,electric motors,generators,inductors, magneticrecording heads, and magnetic assemblies. It is made offerromagneticmetal such as iron, orferrimagneticcompounds such asferrites. The high permeability, relative to the surrounding air, causes themagnetic field linesto be concentrated in the core material. The magnetic field is often created by a current-carrying coil of wire around the core. |
