S3 – movement from electricity

Last week we looked at using electricity to get things moving. We looked at examples of an electric bell and the movement of a current-carrying bar of copper in a magnetic field. We’ll be taking an electric motor apart this week to see how it works but in the meantime, here is a link to an animation of an electric buzzer (same idea as the electric bell).

If you want to read someone else’s explanation of how an electric motor works, you could go here or here. There are animations of a dc electric motor here and here (this is the example I used in class).
