Hard | Soft Magnetic Materials | Properties | Applications

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 …

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 …
