Wahoo spoke magnet for speed and cadence

I lost the spoke magnet for my Wahoo speed and cadence sensor. Is there anyway to buy it separately from the unit, or will any spoke magnet do the trick?

Any magnet will work. I went to hobby lobby and bought some to glue onto my disc wheel.

Looks like you can buy them on Nashbar.
