The ferrite core has very low electrical conductivity which reduces the eddy current in the core, resulting in very low eddy current loss at high frequency. Hence they can be used in high-frequency applications. The Ferrite material is very cheap as it is almost made up of iron rust and is very resistant to corrosion.

Adding an iron core inside the coils focuses and magnifies the flux to make for a more efficient transfer of energy from primary to secondary. This is because the permeability of iron is much higher than that of air. If we think of electromagnetic flux like a bunch of cars going from one place to another, wrapping a coil around an iron core is ...

This is even harder than pig iron. Wrought Iron/ Malleable Iron. Wrought iron is the purest form of iron available commercially available and is prepared from cast iron by heating cast iron in a furnace lined with Haematite (Fe 2 O 3). The Haematite reacts with Carbon in the cast iron to give pure iron and carbon monoxide gas which escapes.

An iron core placed in a current carrying solenoid will be magnetized, and will contribute its field to that of the solenoid. This process will produce a momentary changing flux of field through the coil which will induce a voltage in the coil which tends to oppose the change in flux. If the coil is driven by an AC source, this opposing voltage ...
