Electrodynamics Introduction
1. Generators convert mechanical energy to electrical energy.(by you making things move, electricity is created)
You put in petrol, and the generator gives you electricity.
2. Motors convert electrical energy to mechanical energy.
(motors use electricity to make things move for you)
You put in electricity, and the motor gives you a spinning motion.
This "spinning motion" is then used for drills, washing machines, hairdryers, etc.
3. Motors and Generators both involve a coil that rotates in a magnetic field.
4. The hand rules described here all use conventional current, i.e. flow of positive charge from positive to negative.
5. All hand rules are swopped if electron flow is used.
