Magnetic Pole Tester | Non-Contact N/S Polarity Identification Pen
A compact non-contact magnetic pole tester designed for fast and accurate identification of north and south magnetic polarity. Featuring high sensitivity, clear LED indicators, and a pocket-sized design, this tester is ideal for motor assembly, magnet inspection, and magnetic quality control.
This magnetic pole tester provides a simple and reliable way to identify the north (N) and south (S) poles of magnetic objects without physical contact. Designed for technical, industrial, and workshop use, it helps ensure correct magnet orientation during assembly, inspection, and testing processes.
Using high-sensitivity magnetic detection, the tester clearly distinguishes magnetic polarity through intuitive LED indicators. Its non-contact operation protects both the tester and the magnetic component, making it suitable for delicate or precision applications.
The slim, handheld design allows easy one-hand operation and convenient portability. This makes the tester especially useful for production lines, motor and coil assembly, magnetic device inspection, and troubleshooting incorrect magnetisation or assembly errors.
Typical applications include:
-
Magnetic pole identification (N/S polarity)
-
Motor and coil assembly
