Magnetic coils

WebSo does the bulb light up when there's a changing magnetic field because: a moving electromagnetic field will exert a force on the free electrons of a wire to move; moving electrons is the definition of current; thus the bulb lights up. The force applied depends on the direction of the changing magnetic field, thus changing the way current flows. WebMagnetic Coil - an overview ScienceDirect Topics Magnetic Coil When the magnetic coils are turned on, persistent currents also are induced in the inside surface of the shield, which prevents the levitation magnetic field from penetrating the shield.
