Permanent magnet sucker is an important function of magnetic material. It has been widely used in modern industry and science and technology. People used by low coercivity permanent magnetic separator manufacturer in Shandong, the classification for magnetic coercivity of less than 100A / m (about 1.250e) is called a soft magnetic Branch; coercivity of between 100-l000A / m (1.25-12.50e) is called a semi-hard magnetic materials; coercivity greater than 1000A / m (12.50e) called hard magnetic materials. Hard magnetic materials have been magnetized to saturation, after removing the external magnetic field, is still able to retain their permanent magnetic separator magnetic sacrifice, it is also known as permanent magnetic materials or magnetic materials. When the permanent magnet sucker closed, no magnetic force. The so-called strong permanent magnet sucker closed magnetic circuit means is blocked. There is no pole. When the magnetic circuit is not closed, but in the open state when prices Shandong permanent magnetic separator, permanent magnet sucker thrown on both ends of the pole faces, namely N and S poles. The magnet poles to produce a magnetic field in its vicinity. The magnetic field generated by the magnetic poles, always by the N pole to the S pole, inside the magnet, the magnetic field whose direction opposite the direction of Shandong permanent magnetic separator, it acts as demagnetization, so called demagnetizing field, permanent magnet sucker has a demagnetization function. The size of the demagnetizing factor of the magnet shape and size related.
