Year 7 generate their own electricity

Year 7 are coming to the end of a topic on renewable energy resources, and today we found out how generators actually work. We know that turbines drive generators to make electricity, but how?

Its all about magnets and coils of wire. Did you know that if you move  a magnet near a wire you can make the electrons in the wire move – and moving electrons = electricity! So that’s what we did. We moved magnets inside coils. We tried big and small magnets, thick and thick wire, lots of coils, coils round things, bare coils… and we measured how many milliamps of electricity we could generate. The winners were  Tom, Rebecca and Izzy, with a massive (OK, modest) 0.47 milliamps of current. Here they are working on their challenge.
