A ferromagnetic material has a spontaneous magnetic moment- magnetic moment even in zero applied magnetic field this means that electron spins and magnetic moments are arranged in a regular manner. Consider a paramagnet with a concentration of N ions of spin S. Given an internal interaction tending to line up the magnetic moments parallel to …

Scalar and Vector fields

In this article, learn what are Scalar and Vector fields. We know that many physical quantities like temperature, electric or gravitational field, etc. have different values at different points in space, for example, the electric field of a point charge is large near the charge and it decreases as we got farther away from the …
