The motor effect is also utilised in a variety of other applications such as [[cathode ray]] tubes in [[televisions]] (in many rear screen projectors electromagnets are used in the deflection system), in electron microscopes (electromagnets are used to accelerate electrons), in [[loudspeakers]] (a coil is wrapped around a magnet, the alternating current in the coil causes it to be deflected in and out producing sound waves) and in [[galvanometers]]. | The motor effect is also utilised in a variety of other applications such as [[cathode ray]] tubes in [[televisions]] (in many rear screen projectors electromagnets are used in the deflection system), in electron microscopes (electromagnets are used to accelerate electrons), in [[loudspeakers]] (a coil is wrapped around a magnet, the alternating current in the coil causes it to be deflected in and out producing sound waves) and in [[galvanometers]]. |
