Drop a magnet through a copper tube and it falls in slow motion — no brakes, no power, no contact. The moving magnet stirs up eddy currents in the copper, and those currents push back and brake the fall. The same trick, scaled up, brakes trains and roller coasters smoothly with nothing to wear out.
