Magnetic Pole detector

The N-audio polarity detector is a handy tool for luthiers, guitar pickup builders, and anyone involved in electronic guitar rewiring. This tester quickly identifies the north and south poles of any magnet. Simply place the sensor tip near the guitar pickup, and the LED indicator will reveal the magnet’s polarity.

Why Use a Magnetic Pole Detector for Guitar Pickups?

Correct magnetic orientation is important for effective hum cancellation when using two single-coils in parallel. When two pickups with opposite magnetic fields are wired together, they provide a hum-canceling effect that reduces the noise. In a standard set of Stratocaster pickups, this tool quickly identifies the middle pickup by its opposite magnetic polarity.

Additionally, you can split a humbucker to pair one of its coils with another single-coil pickup. Wiring the coil that has the opposite magnetic field to the single-coil ensures proper hum cancellation.

Why Choose the N-audio Polarity Detector?

Unlike many testers on the market that use strong neodymium magnets, the N-audio magnetic pole detector features a high-sensitivity electronic sensor. This sensor detects magnetic force without altering the properties of Alnico magnets commonly used in guitar pickups, preserving their original tone. Due to an ultra-low standby current of just 4 µA, a single CR2032 battery can last up to 10 years when idle.

This device is equally effective for identifying magnetic polarity or locating hidden magnets. The small sensor tip easily fits into narrow spaces, making it useful for DIY projects, custom component assembly, and various magnetic field applications.
Together with the N-audio Guitar Pickup Phase Checker, you have everything for proper guitar pickup tech work.
