Question

What is the main parameter to distinguishing two types of magnetic materials namely Soft And Hard?

Answer 1

Soft materials:

1. Soft magnetic materials are those that can be easily magnetized or demagnetized.
2. We typically have less than 1000 Am-1 intimidation.
3. They are primarily used to enhance and/or channel the flux generated by an electric current.

Hard materials:

1. Hard magnetic materials are those that have a larger area enclosed by their Hysteresis loop.
2. These materials are manufactured as permanent magnets.
3. Hard magnetic materials have a high remnant magnetization and coercivity.

Parameter:

1. Remanence, also known as remanent or residual magnetization, is the tendency of a ferromagnetic material to maintain net magnetic domain alignment after the effect of an external magnetizing field is removed.
2. Soft materials have a low remanence, whereas hard materials have a high remanence.
