Why are magnetic keepers used to store magnets?

Explanation

### Step-by-Step Solution:

1. **Understanding Bar Magnets**: Bar magnets have two poles - a north pole and a south pole. When storing these magnets, it is important to keep them in a way that maintains their magnetic properties.

2. **Placement of Magnets**: When storing bar magnets, they are typically placed side by side. The opposite poles (north and south) should be positioned facing each other. This arrangement helps to maintain their magnetic strength.

3. **Use of Magnetic Keepers**: Magnetic keepers are materials that are placed across the poles of the magnets. They are usually made of soft iron or similar materials. The keepers connect the north and south poles of the magnets.
