The B-H curve (i) and (ii) shown in fig., associated with
The B-H curve (i) and (ii) shown in fig., associated with
- A. (i) diamagnetic and (ii) paramagnetic substance
- B. (i) paramagnetic and (ii) ferromagnetic substance
- C. (i) soft iron and (ii) steel respectively
- D. (i) steel and (ii) soft iron respectively
Step-by-step solution
The B-H curves for soft iron and steel are both ferromagnetic hysteresis loops. Soft iron has a narrow, tall loop (low coercivity and high permeability), while steel has a wider, shorter loop (higher coercivity). Typically, in such diagrams, curve (i) represents soft iron and curve (ii) represents steel.
