To demagnetize magnets, you can follow these steps:

1. Rough handling: By subjecting the magnet to rough handling, such as dropping it or hitting it against a hard surface, the alignment of its magnetic domains can be disrupted, leading to demagnetization.

2. Heating: Another method is to heat the magnet to a high temperature. This causes the magnetic domains to become disordered, resulting in demagnetization. However, it is important to note that excessive heating can permanently damage the magnet.

3. Magnetizing in the opposite direction: By applying a strong magnetic field in the opposite direction to the magnet's original magnetization, the alignment of its magnetic domains can be reversed, leading to demagnetization.

Therefore, the correct answer to the question is option (4) All the above, as all three methods mentioned can be used to demagnetize magnets.
