Spinning it at 1575.42 Million RPS would create a 1575.42 MHz radio wave. That specific frequency is used by the GPS - so by doing this you'd be interfering with the reception of GPS signals, which is the illegal act you'd go to jail for here.
Pretty sure you'd only have to spin half that fast, you'd get two magnetic cycles per rotation. Though if you flipped one of the magnets (or better yet, removed one) you'd need the 1575+ million rotations but get a stronger radiation (I think, though not positive).
