What happens to the current when a ferromagnetic material is introduced within an inductor?
2.
What is the relation between the flux and the magnetizing current when a ferromagnetic core is introduced within the inductor?
3.
What happens to the effective inductance when a ferromagnetic core is introduced?
4.
A laminated steel ring is wound with 200 turns. When the magnetizing current varies between 5 and 7 A, the magnetic flux varies between 760 and 800 Wb. Calculate the inductance of the coil.
5.
Calculate the number of turns in an inductor with a ferromagnetic core when the inductance is 4000 H, the current changes from 5A to 7A and the flux changes from 760 to 800 Wb.
