John shows you how electric motors work! –

No modern home should be without one – or maybe a dozen. You’ll find an induction motor in the fan, fridge, vacuum cleaner, washing machine, dishwasher, clothes drier, and the little pump that circulates water in the fish tank to stop the water turning green and the fish going belly-up. Chances are there’s also one in the air conditioner – unless it’s a particularly high-tech one.
