Suggest some ways to prevent from demagnetisation of magnets. (2024)

To prevent the demagnetization of magnets, we can follow these steps:

1. Avoid Heating the Magnet:
- Magnets lose their magnetic properties when exposed to high temperatures. Therefore, it is essential to keep magnets away from heat sources.

2. Do Not Hammer the Magnet:
- Physical impact can disrupt the alignment of the magnetic domains within the magnet, leading to demagnetization. Avoid hammering or applying force to the magnet.

3. Prevent Dropping from Heights:
- Dropping a magnet from a height can cause it to lose its magnetism due to the shock. Always handle magnets carefully to prevent them from falling.

4. Keep Away from Electronic Devices:
- Electronic devices such as televisions, mobile phones, and ATM cards can interfere with the magnetic field. It is advisable to keep magnets away from these devices to prevent demagnetization.

5. Store Magnets Properly:
- When storing bar magnets, place them side by side with their opposite poles facing each other (north pole to south pole). This arrangement helps maintain their magnetic properties.

6. Use Keepers:
- When storing magnets, especially bar magnets, use keepers (made of wood or iron) across the poles. This helps to preserve the magnetism by providing a closed magnetic circuit.

7. For Horseshoe Magnets:
- When storing horseshoe magnets, place a single keeper across the poles. This helps to maintain the magnetic field and prevents demagnetization.

Summary:
To prevent demagnetization of magnets, avoid heating, hammering, or dropping them, keep them away from electronic devices, store them properly with opposite poles together, and use keepers for added protection.
