उत्तर
When magnets are not in use they should be kept and stored in magnetic keepers. The magnetic keeper is a piece of soft iron. A magnetic keeper has cardboard with one or two iron soft pieces. Two magnets are placed in such a way that their opposite poles are close to each other and then a soft iron keeper is attached to it.
