The permanent magnetic material is characterised by :
The correct answer is: (B) Broad hysteresis loop. Permanent magnetic materials have a broad hysteresis loop, indicating high retentivity and coercivity. This allows them to retain magnetism for a long time. Such materials are also generally hard and used in making permanent magnets like bar magnets and compass needles.

A permanent magnetic material retains magnetism for a long time. It is characterized by a broad hysteresis loop, which indicates high retentivity and coercivity—essential properties for maintaining strong magnetization. Such materials are hard to demagnetize, making them ideal for permanent magnets.
Answer: (B) Broad hysteresis loop.
