Magnet to stop wires from twisting?

Hello, I am currently designing a robot that will have, well, a lot of circular motion when completed. Could I solder wires to thin and bendable magnets to transfer power, that can ride along an outer edge as the robot spins? If so, what type of magnets will I need?

Thanks everyone! Sounds like ill go for the headphone jack!

A little dab of conductive graphite grease can help with keeping the contacts reliable inside the headphone jack. Just don't use too much or it will bridge between the contacts!
