In order for a magnet to scramble a magnetic strip, it's pretty much going to have to come in direct contact with it. As a matter of fact, the magnetic field emitted by a cell phone can actually demagnetize a credit card if it's allowed to be in direct contact with the magnetic strip for along enough period of time.
