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 …
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 crystal structure which means that …
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 paths and hence the induced …
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. …
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 and DC generators). The induced EMF …
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 …
A closed path followed by magnetic flux is known as a magnetic circuit. In a magnetic circuit, flux starts from one point and finishes at the same point. A magnetic circuit usually consists of magnetic materials having high permeability such as iron, soft-steel, etc. since they offer small opposition to magnetic flux. The magnetic …
