The coercive force in a ferromagnetic material is related

1. area enclosed by the B–H loop
2. intercept on the negative H-axis of the B–H loop
3. intercept on the positive B-axis of the B–H loop
4. maximum value of B on the B–H loop

The coercive force in a ferromagnetic material is related intercept on the negative H-axis of the B-H curve.
