The magnetic effect of electricity is used in a variety of applications, including electric motors and generators, transformers, electric bell, loudspeakers, headphones, and televisions. Electric motors use the magnetic effect of electricity to create rotational motion, while generators use the rotational motion to produce electricity. Transformers use the magnetic effect to step up or step down the voltage of an alternating current. Electric bells use the magnetic effect of electricity to create a ringing sound. Loudspeakers and headphones use the magnetic effect of electricity to convert electrical energy into sound waves. Finally, televisions use the magnetic effect of electricity to create an image on the screen.
