State ways to induce current in coil
WebAug 13, 2013 · Then by either moving the wire or changing the magnetic field we can induce a voltage and current within the coil and this process is known as Electromagnetic … 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.
