Solution
| Paramagnetic substance | Diamagnetic substance |
| 1. A paramagnetic substance is feebly attracted by a magnet. 2. For a paramagnetic substance, the intensity of magnetisation has a small positive value |
1. A diamagnetic substance is feebly repelled by a magnet. 2.For a diamagnetic substance, the intensity of magnetisation has a small negative value. |
