Flux pumping is a way of using magnets to move energy from one place to another. It works by having a magnet that is shaped like a doughnut, with a hole in the middle and wires wrapped around the outside. When a current flows through the wires, it creates a magnetic field that is concentrated inside the doughnut, and pushes energy out of the middle like a pump. This energy can be used to power electric motors, light up lights, and do many other things.
