Wheel magnet

[Andy_G]

On my Trek i use a Bontrager DuoTrap Digital Speed/Cadence Sensor, but over the weekend im putting together a rear wheel for my turbo/rollers.
The only issue i have is the wheel magnet on my normal wheels i use:

But i cant find anyone that has them in stock, so can i use any other wheel magnet.

Thx.

Not too sure but I think any magnet is fine.
