Suppose a 0.3 m long solenoid with cross-sectional area of 12 cm 2, N 1 = 1400 turns and N 2 = 20 turns, produces a mutual inductance 'M'. Now if there are two inductors namely 0.1 H and 350 mH are connected in parallel. Effectively having opposing magnetic fields which results to a mutual inductance. Use the value of 'M' to calculate the overall inductance of the parallel combination.

Ferromagnetism

Ferromagnetism is a mechanism by which some materials show magnetic properties. Iron and magnetite, an oxide of iron, are two naturally occurring materials that show the property of ferromagnetism. The word ferromagnetism is derived from the Latin name of iron, "Ferrum" as it was the first observed material to show such property. The property of ferromagnetism is shown by only a few substances such as iron, nickel, cobalt, and their alloys. Some transition metals and alloys of rare-earth metals also show ferromagnetism.
