Hysteresis loops for two magnetic materials \( A \) and \( \mathrm{B} \) are given below
(A)
(B)
(1) Coercivity of \( A \) is greater than \( B \) but retentivity of \( B \) is greater than \( A \);
(2) Coercivity and retentivity of \( B \) is greater than \( A \);
(3) \( A \) is suitable for making permanent and \( B \) is suitable for making electromagnet
(4) Both (2) and (3)
