neodymium

The strongest permanent magnets in the world are neodymium (Nd) magnets, they are made from magnetic material made from an alloy of neodymium, iron and boron to form the Nd2Fe14B structure

Energy

Moving a magnet around a coil of wire, or moving a coil of wire around a magnet, pushes the electrons in the wire and creates an electrical current. Electricity generators essentially convert kinetic energy (the energy of motion) into electrical energy.
