For a magnet to be used as propulsion, you'd need something for it to pull or push against.
Finding a likely target seems impossible. The way magnetism drops off with distance means it would only be useful when you were already there (or just starting out).
Also the magnetic field in this case is only lasting a tiny fraction of a second, which would be an issue for propulsion.

- mathnmusic 8y agoI guess what OP meant is interaction with earth's magnetic field to get out of its gravitational pull.
