Web6 aug. 2024 · If the coil is wound onto a ferromagnetic core a greater inductance will result as the cores permeability will change with the flux density. However, depending upon … When the core is subjected to a changing magnetic field, as it is in devices that use AC current such as transformers, inductors, and AC motors and alternators, some of the power that would ideally be transferred through the device is lost in the core, dissipated as heat and sometimes noise. Core loss is commonly termed iron loss in contradistinction to copper loss, the loss in the windings. Iron losses are often described as being in three categories: recorded snowfall amounts
