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 soft magnetic materials […]
Ferromagnetic materials have a crystal structure which means that they are made up of crystals. Every crystal of a ferromagnetic substance has a particular direction along which it offers high permeability and is, therefore, most easily magnetized. Such axes, along which the crystals have high permeability and are more easily magnetized, are called the “preferred”
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 currents are set up
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: Self Induced EMF The EMF induced in a coil due to change of flux produced by it linking with its own turns is known as self-induced EMF. Consider
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 flux is
