Magnetism is caused by the motion of electrical charges (electrons) in an atom. Each electron acts as a microscopic magnet. In Iron, Cobalt and Nickel these electrons spin in the same direction which makes these atoms strongly magnetic. (National Geographic Society, see under ‘Magnetism’).
Sound can be embedded in a magnetic tape, is this why houses could contain the lives of previous residents in the atomic structure of their walls?
Does the electron spin in an atom cause an atom to have the properties of a magnetic tape?.
