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. WebAn electric field (sometimes E-field) is the physical field that surrounds electrically charged particles and exerts force on all other charged particles in the field, either attracting or … phipps housing rentals
