One experiment to verify the law of magnetism is to use a simple setup with two bar magnets.
First, place one bar magnet on a flat surface and mark one end as the north pole and the other end as the south pole. Then, take the second bar magnet and bring one end close to the north pole of the first magnet.
If the two north poles repel each other, and the north pole of the second magnet is attracted to the south pole of the first magnet, this demonstrates the law of magnetism that like poles repel and opposite poles attract.
To further verify the law of magnetism, you can also try reversing the orientation of one of the magnets and observe how the poles interact. This should confirm the behavior predicted by the law of magnetism.
Additionally, you can measure the force of attraction or repulsion between the magnets using a spring scale or a balance to quantify the strength of the magnetic force, which should also align with the law of magnetism.

Experiment to Verify the Law of Magnetism
Law of Magnetism: The magnetic force between two magnetic poles is directly proportional to the strength of the poles and inversely proportional to the square of the distance between them.
Materials:
- Two bar magnets
- Digital force gauge
- Ruler
- Stand with adjustable height
Procedure:
1. Setup the Experiment: Place the two bar magnets vertically on the stand, with their north poles facing each other. Adjust the height of the stand so that the magnets are at a known distance (d) from each other.
2. Measure the Force: Attach the force gauge to the top of one of the magnets. Gently touch the opposite pole of the other magnet to the force gauge and gradually increase the distance until the maximum force is recorded. Record the force (F) in newtons.
3. Repeat Measurements for Different Distances: Repeat steps 2 and 3 for multiple different distances between the magnets, ensuring that the magnets are aligned with their poles facing each other. Record the force values and distances for each measurement.
4. Plot a Force vs. Distance Graph: Plot the force (F) on the y-axis against the square of the distance (d²) on the x-axis. The graph should show a linear relationship.
5. Calculate the Slope: Determine the slope of the best-fit line to the plotted data. The slope represents the constant of proportionality (k) in the magnetic law.
Analysis:
The slope of the graph should be equal to the constant of proportionality (k) in the law of magnetism:
```
F = k - (m1 - m2) / d²
```
where F is the force, m1 and m2 are the strengths of the magnetic poles, and d is the distance between them.
By comparing the slope (k) obtained from the experiment to the theoretical value of the constant of proportionality, you can verify the law of magnetism.
Expected Results:
The slope of the force vs. distance graph should be a positive value, indicating that the force between the magnets increases with increasing strength of the poles and decreases with increasing distance. The experimental value of the constant of proportionality should be close to the theoretical value, supporting the law of magnetism.
