I get that if you heat up a magnet, it loses its magnetism, and I know they can be remagnetised through certain methods, but I feel like that would essentially lower the life expectancy of said magnets, and cause a danger to people/items due to the sheer size of some of the industrial magnets used. Is there some sort of other method? What other ways would there be to demagnetise/remagnetise on command?

EDIT: Turns out electromagnets are a thing that exists. Not even something I would have considered honestly. Learn something new every day lol.
