![]() How does it identify the north and south poles of a permanent magnet? ![]() This is a great new gadget we are carrying! Essex Magnet Wire - Winding Wire - Enameled.Magnet Pole Detector - Identifier - Tester.Magnetic Tools-Films-Fluids Gadgets & Science Kits.N48 - N50 - N52 Strongest Rare Earth Neodymium Magnets.Neodymium Arc & Wedge Rare Earth Magnets.Neodymium Sphere & Ball Rare Earth Magnets.Neodymium Ring & Tube Rare Earth Magnets.Neodymium Magnets With Countersunk Holes.Neodymium Cup & Hook Magnets - Magnetic Cups.Neodymium Diametric Disc & Cylinder Magnets.Neodymium Disc & Cylinder Rare Earth Magnets.Rare-earth magnet steel is easy to demagnetize: When the permanent magnet material is subjected to vibration, high temperature and overload current, its magnetic permeability may decrease, or demagnetization phenomenon occurs, which reduces the performance of the permanent magnet motor.The impact on the power supply system is large, requiring a large capacity of the power supply system. The starting current is more than 10 times the rated current. ![]() EARTH MAGNET FULL
