Here's a video of someone explaining it. Kinda:
You'd need to use two small n52 magnets and drill a space the size and depth of the magnet into the ear housing and the stalk so that they line up (being careful not to drill too far if you have a hollow RF stalk with the RF light wire in it, you don't want to cut through those wires. Then match the polarities and glue the magnets in place. I'll get you a picture of my setup when I get back from work.
