Magnetic Pole detector
The N-audio Magnetic Pole Detector is a compact tester that instantly identifies the magnetic polarity (north and south poles) of guitar pickups, permanent magnets, speakers, electric motors and many other magnetic assemblies. Unlike many conventional magnetic polarity testers, it contains no built-in magnet, making it ideal for testing sensitive Alnico pickup magnets.
It is especially useful for luthiers, pickup builders and guitar technicians, but its applications extend far beyond guitar work. Whenever you need to determine the magnetic polarity of a magnet, this tool gives you a clear and immediate LED indication.
More Than a Guitar Pickup Tester
Although widely used for guitar pickups, the N-audio Magnetic Pole Detector is a general-purpose magnetic polarity tester. It can be used to check pickup pole pieces, locate hidden magnets inside electronic devices, inspect electric motors or determine the magnetic polarity of permanent magnets in workshop, laboratory and industrial applications.
The slim sensing tip makes it especially practical in narrow or hard-to-reach spaces where many conventional magnetic polarity testers simply do not fit. This allows you to check magnetic polarity exactly where you need it, even inside compact devices, pickup cavities or tight mechanical assemblies.
Why Magnetic Polarity Matters for Guitar Pickups?
When two guitar pickups are used together, magnetic polarity becomes important. For proper hum cancellation, two single-coil pickups usually need opposite magnetic polarity. The Magnetic Pole Detector instantly shows which pickup has the opposite magnetic pole. For example, it makes identifying the correct magnetic polarity for a Stratocaster middle pickup quick and effortless.
It is also very useful when splitting humbuckers. By identifying the magnetic polarity of each coil before wiring, you can choose the correct coil to combine with another pickup and maintain hum-cancelling operation. Instead of installing the pickups, restringing the guitar and discovering a noise or phase problem later, you can verify the magnetic polarity before final assembly.
Safe for Alnico Pickups
Many magnetic polarity testers use a permanent magnet as part of their operation. While this approach works well for general-purpose measurements, bringing another magnet close to sensitive Alnico pickups is generally best avoided.
The N-audio Magnetic Pole Detector works differently. Instead of using another magnet, it uses a highly sensitive magnetic field sensor that simply detects the existing magnetic field. Because it introduces no magnetic field of its own, it is ideal for testing sensitive Alnico pickup magnets.
Simple LED Indication
Just place the narrow sensor tip close to the pickup pole piece, speaker magnet, motor magnet or any permanent magnet. The LED instantly indicates whether the detected pole is North or South. There are no settings to adjust, and not even a power switch. The result is immediate, visual and easy to understand.
Complete Pickup Testing with the Guitar Pickup Phase Checker
Magnetic polarity is only one part of correct guitar pickup wiring. The other is the pickup's electrical phase. That is why many customers buy the N-audio Magnetic Pole Detector together with the Guitar Pickup Phase Checker. The Magnetic Pole Detector shows the north and south magnetic poles of the pickup. The Pickup Phase Checker verifies the electrical phase of the pickup before the soldering work is finished.
Together, they eliminate guesswork during pickup wiring. You can check magnetic polarity, confirm electrical phase and wire the guitar correctly the first time. For luthiers, repair shops, pickup builders and serious DIY guitar enthusiasts, the two tools make a very useful workbench bundle.
