What Happens When You Spin a Motor With No Battery?<\/h3>\n

Hook a battery up to a motor, and it spins.<\/p>\n

\"\"<\/p>\n

“Well, duh,” you might be thinking. But what if you skip the battery and spin the motor’s shaft by hand instead? What do you think would happen? It turns out this is where one of the great secrets of electricity is hiding.<\/p>\n

It’s super easy: just pinch the motor’s shaft and spin it. Fingers alone aren’t great for getting up to speed, though, so I pressed a stick against the shaft and rolled it back and forth. Rubbing it with the stick makes it spin much faster than fingers can.<\/p>\n

Then I connected the motor to an ammeter and spun the shaft. Whoa, current flowed! There’s no battery anywhere, and yet electricity is being made. Check out the video here.<\/p>\n
