Internal MagSpeed Scroll Wheel Assembly
The MagSpeed system relies on an electromagnetic coil to flip the magnetic polarity of a stator, which either attracts or ignores the steel wheel's internal teeth. If the wheel remains in ratchet mode regardless of input, the coil has likely suffered an open circuit or the internal magnet has lost its ability to toggle states. Replacing the entire assembly is required as the electromagnetic components are precision-aligned and sealed during manufacturing.
