Is it possible to make the magnets lose it magnetic field permanently?
I heard that prolonged exposure to heat can move the ions around making it loose its magnetic field. repetitive shock (as in hitting it with a hammer) also has this effect. Usually old magnets tent to have lost magnetism because of all hitting and banging that they are used under. Bigger magnets loose their strength faster because they tend to slam onto the metal or other magnets faster and with more force. Usually when buying strong magnets they give you some less powerful magnets known as “keepers” these are put there to regulate the flow of ions in the magnet if put in the right position, thus keeping the magnet from loosing it’s strength during transport and keeping it’s “shelf life”. It is wise to keep this “keeper” so that your magnet stays in better condition when you are not using it.
