    A motor is DC so when the magnet rotates, the slip ring swaps the contacts to keep it moving in the same direction (current that is) and a Generator is AC so the contacts dont swap every half turn but the current reverses every half turn. Is this correct? I thought EM induction could only happen with an AC supply, so why does the motor work. im a bit confused! Help!
