Question

5. How can the self-demagnetisation of magnets be prevented
​

Answer 1

Demagnetization is the process whereby a magnet loses all of its magnetic properties. The magnet most prone to demagnetisation is the ferrite magnet due to the alloy it is made of, however all magnets can be demagnetized.

To avoid demagnetizing we should follow these guidelines:

   

(1)Separating your magnets.

(2)Keep away from high temperatures.

(3)Store with a keeper.

(4)Avoid electrical currents.

(5)Store in pairs.

(6)Keep magnets in a dry place.

(7)Avoid damaging the magnet.
