I cannot for the life of me figure out what the heck a "power magnet" is. I have owned wired computers and wireless computers and have never given any thought whatsoever about whether the magnet on one of my wheels might not work with the wired or wireless sensor. The mechanism is very simple, as the magnet passes the sensor it operates a switch in the sensor sending a signal. With a wired sensor, it is a simple off/on/off and the computer interprets the frequency. A wireless setup involves a sensor that sends the signal to the computer via some sort of wireless protocol. As long as the sensor and the head unit can communicate with each other, the signal gets through. All that the magnet does is magnetically close the switch in the sensor as it passes by
