A bar magnet has no markings to indicate its poles. How would you find out near which end is its north pole located?

Explanation

To determine which end of an unmarked bar magnet is its north pole, you can follow these steps:

### Step-by-Step Solution:

1. **Obtain a Second Magnet**: Get another bar magnet that has its poles clearly marked. This magnet will help you identify the poles of the unmarked magnet.

2. **Identify the North and South Poles of the Second Magnet**: Look at the marked magnet and identify which end is the north pole (N) and which end is the south pole (S).
