Soft and Hard Magnetic Materials

Properties and Applications of Soft Magnetic Materials   Materials which have a steeply rising magnetization curve, relatively small and narrow hysteresis loop and consequently small energy losses for each cycle of magnetization are called soft magnetic materials.   Soft magnetic materials are, therefore, employed in building cores for use in alternating magnetic fields. The commonest …

Hysteresis Loss | Loop

Hi friends, in this article, I am going to discuss the hysteresis loss, hysteresis loop in the magnetic material in and their significance. So let us start. A ferromagnetic material consists of local regions called ‘domains,’ each of which is spontaneously magnetized. In an unmagnetized material, the directions of magnetization in different domains are different. …

Lenz’s Law

Lenz’s Law   Lenzs law is used to determine the direction of induced emf in the conductor or coil.   According to Lenz’s law, the electromagnetically induced emf and hence current flows in the conductor or coil in such a direction that the magnetic field set up by it always oppose the cause, which produces …
