Question

explain the difference between a soft and a hard magnetic material?​

Answer 1

Answer:

Difference between Hard and Soft Magnetic Material. 1. Hard magnetic material have large hysteresis loss. Soft magnetic material have low hysteresis loss. 2. Domain wall moment is difficult in hard magnet whereas domain wall moment is relatively easier in soft magnet. 3. In the first, coercivity & Retentivity are large.

Answer 2

Explanation:

Since soft magnetic materials can be demagnetized at low magnetic field, coercivity Hc is low. ... These materials are called hard magnetic materials, and are suitable for applications such as permanent magnets and magnetic recording media. Hard magnetic materials have high magnetocrystalline anisotropy.
