1. Welcome Scientists Today: Complete Building a Motor Activity Motors Vs. Generators Electricity and Magnetism Mind-Map

2. We Know That Electric Currents Produce Magnetic Forces So moving electrons create a magnetic force And magnetic fields can interact to create motion (motors!) But what about the opposite? What is the effect of magnetic force on electrons? http://phet.colorado.edu/en/simulation/legacy/faraday https://www.youtube.com/watch?v=yA8gZM3fghc So magnetic fields can cause electrons to move in a wire And electrons moving in a wire is called… Electricity!!! – so the reverse process of a motor GENERATES electricity (what do you think we call that? A generator
