Question

Quizplus · Accepted Answer

Permanent magnets can lose their magnetism if they are heated above their Curie temperature or if they are subjected to a physical shock, such as being hit hard. Both overheating and physical impact can disrupt the alignment of the magnetic domains within the magnet, leading to a decrease in its magnetic field.
