Correct Answer: self-demagnetisation
Solution : The correct option is self-demagnetisation .
Magnets are shielded against self-demagnetisation by magnetic keepers. A permanent magnet's internal magnetic domains may become disorganised when subjected to an external magnetic field that is strong enough and moving in the opposite direction. This will lower the magnet's total magnetic strength. The term demagnetisation refers to this action.
