Q. No.There are four light-weight-rod samples \(A,\) \(B,\) \(C,\) \(D\) separately suspended by threads. A bar magnet is slowly brought near each sample and the following observations are noted:
Which one of the following is true?
| (i) | \(A\) is feebly repelled. | (ii) | \(B\) is feebly attracted. |
| (iii) | \(C\) is strongly attracted. | (iv) | \(D\) remains unaffected. |
Which one of the following is true?
| 1. | \(C\) is of a diamagnetic material. |
| 2. | \(D\) is of a ferromagnetic material. |
| 3. | \(A\) is of a non-magnetic material. |
| 4. | \(B\) is of a paramagnetic material. |
