If the B-H curves of two samples of X and Y of iron are as shown below, then which one of the following statement is correct?

Step-by-step solution

For permanent magnet we prefer a material with high retentivity and high coercivity. For electromagnet, we prefer high saturated magnetism, low coercivity and least possible area of hystersis loop. Therefore, X is suitable for making permanent magnet and Y for making electromagnet.
