PHElectric Motor Build: One of the most important inventions consists of only three basic components as shown here: coil, magnet, and a battery with lead wire posts. The wire of the spinning coil has an insulating coating on it- and this coating is carefully scrapped off one side of the thin wire on each end. When current passes through the coil it becomes an electromagnet and the permanent magnet repels it making it spin- as it turns the current goes on and off depending on if the copper wire posts are in contact with the bare wire side (current on) or the part of the wire with the insulating coating intact (current off). When the current is off momentum keeps the rotation going until the next push. The physics of converting electric energy to rotational kinetic energy- and a fun DIY project! ➡️ Follow the link in my profile for information on where to get similar motor kits and other amazing items featured here on @physicsfun #electromagnet #emf #physicsfun #electricmotor #physics #physicstoy #electriccurrent #science #worldssimplestmotor #windings #coils #electromagnetism #Bfield #ampereslaw #scienceisawesome #flux
