The midpoint of the bar magnet with string hanging up, when stationary magnet Fujian join, it will all point to the Earth at both ends of the South and the North, called the finger pointing towards the north end of the North Pole or N-pole, pointing to one end of the South as a guide or S pole. If the thought of a big magnet Earth, the Earth's magnetic north pole is a guide, it refers to the geomagnetic North Pole South Pole. Between the magnet and the magnet poles of the same name with rejection, with different names poles attract. So, compass and Antarctic repulsion magnet join Xiamen, compass and Arctic mutually exclusive, but the relative attraction compass and compass. Why go through after the burning of the magnet loses its magnetic properties of? Magnet problem - Some time ago I had a client ask Foshan magnet supply, why buy a powerful magnet over after the fire, there is no magnetic, and said our product quality problems, said magnet is a permanent magnet to the, does not appear demagnetization phenomenon fishes, encountered this problem really can not blame our customers are the reason we do not have to explain to customers clear, powerful magnets, also known as NdFeB magnets, rare earth metal praseodymium, neodymium, dysprosium and other rare elements mixed sintered into the main features of the magnetic strong, very versatile, the disadvantage is not temperature, general theoretical point temperature is 80 degrees NdFeB magnets, actually about 60 degrees, the highest temperature of NdFeB is 200 degrees degree, after we explained the customers understand the truth! This is why there will be no fire magnet magnetic phenomenon. Dongguan magnet supply of new Tong Xin magnetic, magnet provided by the Dongguan City Tong Xin magnetic Limited.
