Narrative about electric motors and generators for science

Storyboard Text

  • Ugh this electric motors and generators assignment is killing me! Hey Max, can you help me?
  • Sure bud. What’s the question asking?
  • Thanks Bro, this is really helping!
  • Oh, that’s simple! An electric motor converts electrical energy into mechanical energy and an electric generator converts mechanical energy into electrical energy. Electricity flows through both motors and generators, just in different directions.
  • What about the link between electromagnetism and the functioning of motors and generators?
  • Electromagnetism or electromagnetic induction is the voltage induced by a changing magnetic field.  Voltage can be produced inside of a coiled wire by running a magnet in or out of the coil, or by moving the coil through a magnetic field.
  • Wait, so what even uses electric motors?
  • Dude, so many things use motors. Stuff like the vacuum and the blender, they use one. And the fridge even uses three! On for the compressor, one for the fan and one for the ice maker.
  • The fridge is one of the most useful modern appliances in the house. Not only does it keep food and drinks cold, it also preserves food a lot easier and more conveniently than previous methods of preservation. In the past people would have had to curry or pickle the food to make it last longer.
  • But how is the fridge useful to society?
  • It sure has! When Michael Faraday invented it, it revolutionised the world and the things we use in it. Some of the most influential things invented with an electric motor are, the fridge of course, sewing machine which eliminated the need for  the much less energy efficient power looms and cotton gins, even things like smartphones and air conditioners all use electric motors.
  • Wow! So I guess the electric motor really has changed the world.
