Portable Electronic Magnetic Pole Detector

This magnetic pole detector takes all of the guesswork out of determining the polarity of a magnet by allowing you to instantly and accurately identify where the poles are located on magnet with just the push of a button. When in the presence of a magnetic field this pole tester will emit a beep, and light up red to indiciate a north pole, or green to indicate a south pole. This field tester is also great for making the handling of large, potentially dangerous magnets safer by eliminating the guesswork of identifying the polarities of magnets and how they will react to each other.
