The effect of the magnet on the watch: the general watch is mainly made of steel spring made of iron, nickel and other metals, we know that these two metals will be \"magnetized\" by the magnet, and the attack will also be magnetic after being washed by the magnet, and the material is called \"ferromagnetic material\" physically.
