2017 1 7  Magnetic materials are classified in terms of their magnetic properties and their uses. If a material is easily magnetized and demagnetized then it is referred to as a soft magnetic material, whereas if it is difficult to demagnetize then it is referred to as a hard (or permanent) magnetic material. Materials in between hard and soft are almost

2019 6 11  For understanding the hard magnetic materials, we have to know certain terms.They are as follows Coercivity The capability of a ferromagnetic material to hold up (resist) a peripheral magnetic field without getting demagnetized. Retentivity (Br) It is the amount of magnetism that a ferromagnetic material can maintain even after the magnetic field is decreased to zero.

Magnetic Hysteresis Loop including the B H

The Magnetic Hysteresis loop above, shows the behaviour of a ferromagnetic core graphically as the relationship between B and H is non linear. Starting with an unmagnetised core both B and H will be at zero, point 0 on the magnetisation curve.. If the magnetisation current, i is increased in a positive direction to some value the magnetic field strength H increases linearly with i and the flux

Why soft magnetic material is used in transformer?

Why soft magnetic material is used in transformer?

Transformer core requires magnetization, demagnetization and reverse magnetization during operation. The energy expended in doing so in the form of hysteresis losses should be minimum. This corresponds to low coercive force on the magnetization cu

Magnetism

2019 6 6  Magnetism is a class of physical phenomena that are mediated by magnetic fields. Electric currents and the magnetic moments of elementary particles give rise to a magnetic field, which acts on other currents and magnetic moments. The most familiar effects occur in ferromagnetic materials, which are strongly attracted by magnetic fields and can be magnetized to become permanent magnets
