Electronic Magnetic Pole Detector
This electronic Magnetic Pole Detector is easy to find and identify magnet pole
As we know that magnets have both N and S polarities at the same time, and sometimes we want to distinguish the polarity of a magnet or a magnetic field in order to need.
This electronic Magnetic Pole Detector is easy to find and identify magnet pole. It uses 4xGPA76 cell batteries, the electronic probe can identidy magnet pole quickly.
How to use electronic Magnetic Pole Detector?
Press the Probe button, while the light is off, it means that there is no magnetic field, and there is no magnetic pole. Put the probe close to one end of the magnet, if the red light is on, it means that this end is the 'N' pole, and if the green light is on, it means it is the 'S' pole. This magnetic pole detector pen senses the magnetic field and identifies the polarity of the magnet.
Of course, the earth itself is a big magnet, but this electronic magnetic pole detection pen cannot detect it, because the magnetic field of the earth is too weak. You can consider using a compass or another of Dailymag's mechanical permanent magnet pole detectors to find the direction of the earth's magnetic poles.
