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?

Options:

Answer:

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.
