11. Simple a.c. generator
Fleming’s right hand rule gives the sense of the current to be
which means that, at the instant shown in the diagram, terminal Q is the positive terminal of the generator
When the coil has turned through 180°, P will be the positive terminal so the generator gives us alternating current
