Hysteresis, Soft Iron vs Steel & Shielding

In the following graph of flux density versus magnetizing force, coercivity and retentivity are respectively represented by the points

Show answer and solution

Answer: (a)

Retentivity is the value of $B$ left when $H = 0$ . It is the point where the loop cuts the $B$ -axis: point b.
Coercivity is the reverse $H$ needed to make $B = 0$ . It is the point where the loop cuts the negative $H$ -axis: point c.
So the answer is (a): c and b.
