Iron Powder Cores

An iron core, also known as a magnetic core, is a component that produces inductance in electrical circuits or coils. It's also utilized in transformers. Electromagnetic induction generates an electric field by altering the magnetic flux density. Difference between iron powder core and ferrite core The permeability of ferrite core is much higher than that of iron powder core. It is generally used in the manufacture of high frequency transformer and common mode inductor. There are many gaps in the iron powder core as the air gap of the magnetic core, which are generally used for energy storage inductance and differential mode inductance.
