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 Read more…
Hi friends, In this article, I want to ask you some questions: Why CRGO core is used in transformers? How does CRGO core offer high permeability? Can we use CRGO core in motors? If you know, it is fine, if you don’t, keep reading. Ferromagnetic materials have a Read more…
Hi friends, In this article, I am discussing the eddy current loss, eddy current loss formula, its causes and applications. So let us start with our topic. What is eddy current loss? Whenever the magnetic flux linking to conducting material changes, voltages are induced in all possible Read more…
When a ferromagnetic material is placed in a magnetic field, it is magnetized by induction. If we vary the magnetic intensity H of the magnetic field, the magnetic flux density B in the ferromagnetic material does not vary linearly with H i.e. the susceptibility and the permeability of the material Read more…
When the flux linking with a coil (or conductor) changes, an EMF is induced in the coil. This EMF can be induced by the following two ways: By rotating the coil in a stationary magnetic field or by rotating a magnetic field in a stationary coil (as in AC Read more…
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 Read more…
Magnetic Field The magnetic field of a magnet is defined as the region near the magnet within which the influence of the magnet is felt. Magnetic Line of Force The magnetic line of force may be defined as a line along which an isolated N-pole would Read more…
