Give some examples of paramagnetic substances.

Explanation

### Step-by-Step Solution:

1. **Definition of Paramagnetic Substances**:

2. **Characteristics of Paramagnetic Substances**:
- In paramagnetic substances, the magnetic dipoles (due to unpaired electrons) are not perfectly aligned. They tend to be randomly oriented, which means they do not cancel each other out completely.
