how can self _demagnetisationof magnet be prevented
Answers
Answer:
The best method to use in prevention of self-demagnetization of a permanent magnet is by use of a keeper. Keepers were also commonly known as amateurs. They help in storing magnets safely, especially those that have low coercivity ( magnets that are extremely susceptible to stray fields

Explanation:
Demagnetisation 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 demagnetised. To avoid demagnetising your magnet, follow these guidelines:
Separating your magnets
Pulling two magnets apart Make sure you separate any magnets that have become attached to one another by directly pulling them apart. Any other movement to separate the two may damage the magnets and potentially demagnetise them.
Keep away from high temperatures
Very hot thermometer High temperatures are the only way to demagnetise a magnet to a point where it cannot be re-magnetised. All other forms of demagnetisation can be put right by re-magnetising the magnet. For example, using a magnet, without a steel casing to protect it, to retrieve ferromagnetic objects from a plating vat would damage the magnet.
