What is magnetism?

Explanation

### Step-by-Step Text Solution:

1. **Definition of Magnetism**: Magnetism is a physical phenomenon produced by the motion of electric charge, which results in attractive and repulsive forces between objects.

2. **Components of a Magnet**: A magnet has two poles: the north pole and the south pole. These poles are essential for the magnet's properties.

3. **Interaction with Magnetic Materials**: When a magnet is brought close to a magnetic material (like iron), it exerts a force on that material. This force can either attract or repel the material depending on the orientation of the poles.
