Idra wraps a wire around a plastic tube and connects the ends of the wires to a device that measures electric current. When she slides a bar magnet through the tube, north pole first, she sees that a small amount of electric current is produced in the wire. She slides three more bar magnets through the tube north pole first, and a small amount of electric current is produced in the wire each time. A. Predict how the current will change if Idra slides the bar magnets through the tube south pole first.

B. Using the same materials, describe one other way Idra could change the current produced in the wire and predict how the current will change.
