The strip magnet falls in a long, vertical copper pipe from which air is evacuated. In this case, the magnet does not touch the pipe walls. Will the magnet move in free fall?
No, it will not. Due to the electromagnetic induction, an induction current will arise in the copper pipe, the magnetic field of which will be directed towards the magnetic field of the magnet, slowing down its fall.
