Magnets can be demagnetized by heat. Is that true for permanent magnets or materials that have been magnetized?

It’s true for both because permanent magnets are just a special material that has been magnetized. In fact, permanent magnets are often demagnetized more easily than other simpler materials. Anything that spoils the internal order of a material (heat or vibration) can demagnetize it.
