Physics · Para-, dia- and ferromagnetic substances with examples, the effect of temperature on magnetic properties
The hysteresis cycle curve for the material of a permanent magnet is:
The hysteresis cycle curve for the material of a permanent magnet is:
- A. short and wide
- B. tall and narrow
- C. tall and wide
- D. short and narrow
Step-by-step solution
Permanent magnets require materials with high remanence (tall loop) and high coercivity (wide loop) to retain magnetization. Therefore, the hysteresis loop is tall and wide.
