Max was waiting with his friend Josh for the bus to take them too school .
Hey, max you ready for the science test Mr Ceruti made? Apparently, its got questions like compare and contrast an electric motor and generator, I don't even know that means.
Man, that's easy! A motor converts electrical energy into mechanical energy, while a generator makes mechanical energy become electrical energy.
Really Its that simple?!
Yea it is! Mr ceurti told me that in the test we would have to give 3 examples of machines that use electric motors .
Yea fans, electric drills and electric clocks are just a few machines that use electric motors.
And finally what is something that has changed the world that uses an electric motor?
An electric drill because most drills used these days are electric and most trade jobs would use them every day.
Just so you know how to explain the link between electromagnetism and the functioning of motors and generators, it's just when a wire is moved through the magnetic fields a current goes through it. Say a coil of wire was being spun between the two opposite magnets, there is electricity being generated to make the motor work.
I'm just not too sure about how the coal is converted into energy though.
its simple man, There's thermal coal that has been put into a fine powder that we burn to produce water (steam) to spin the turbine in the motor.
