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?.

Can you generate ‘a magnetic repulsion force’ which, for example, could split water into Oxygen and Hydrogen? You would need to ionise the water atoms so that there exists a repulsion between the two types of atoms and not an attraction.

Note that a Maglev train levitates above a rail tract based on a magnetic – repulsion force between the track and the undercarriage of the train.

Rectennas are receiving Antennas that convert electromagnetic waves into electricity. An Infra-red Rectenna is an optical Rectenna which picks up IR light. Rectennas are made out of conductive metals such as copper and aluminium (and graphene) and these conductive materials can be embedded in the framework of the body of the car. As the car is driven (or standing still), the battery is recharged.
