Inch Magnetic Pole Identifier EPID2

Product Description

The epid2 is a compact electronic magnetic pole identifier designed to quickly and accurately determine the north or south pole of a magnet. Simply position the tip near the magnet and press the button; an LED indicates the detected polarity. The 5.75" long tool includes a protective case and features an easily accessible battery compartment for quick battery replacement. The epid2 requires one AAA battery, sold separately, and is designed for use with magnets 1/8" in diameter or larger.

The epid2 magnetic pole detector provides a fast and reliable way to find magnet polarity during assembly, inspection, testing, and experimentation. Quickly finding north and south poles helps ensure magnets are installed in the correct orientation and can prevent polarity errors when building assemblies that require specific attraction or repulsion. It is a useful tool for engineers, technicians, manufacturers, makers, hobbyists, and educators working with permanent magnets. The epid2 can be used for quality control, magnet installation, magnetic assemblies, motors, sensors, prototypes, repairs, classroom demonstrations, STEM projects, and other applications where quickly identifying magnetic polarity is important.
