Why Skin Effect Occurs in Transmission Lines?

The distribution of current throughout cross section of  a conductor is uniform only when DC is passing through it. When Alternating Current(AC) is passing through a conductor, the current is non uniformly distributed over the cross section in a manner that the current density is higher at the surface of the conductor compared to the… Read More »

Spontaneous Magnetism / Magnetization

Spontaneous magnetization is the appearance of an ordered spin state (magnetization) at zero applied magnetic field in a ferromagnetic or ferrimagnetic material below acritical point called the Curie temperature or TC. Heated to temperatures above TC, ferromagnetic materials become paramagnetic and their magnetic behavior is dominated by spin waves or magnons, which are bosoncollective excitations… Read More »
