Most modern electronic products, such as our smartphone, less will be affected by the negative impact of the small magnets, but it is really the case? Matt said, 'we see in daily life of the vast majority of magnets, even on the market that extremely powerful magnets will not harm refers to smart phones',' in fact, in some devices will have a number of very small but play an important role in the magnet. Watch the latest generation of apple, for example, using the magnetic induction wireless charging system. 'in you breathe a sigh of relief, however, started with a magnet on your smartphone row to row before you go to, to know more about something. Matt warned that magnetic field could temporarily interferes with smart phone digital compass and magnetometer, and its serious consequences than you imagine. High temperature resistant magnet is widely applied in industry a magnet type, mainly due to a lot of work in high temperature environment. At a high temperature resistant, in general, the magnet technology after the saturation magnetization of magnet magnetization when in reverse, the magnetic induction intensity is zero needed to reverse the value of the magnetic field strength is called magnetic induction coercive force ( Hcb) 。 But at the moment of magnet magnetization is not zero, but with the reverse magnetic field and magnet magnetization effects cancel each other out. Magnet characteristic which is high temperature resistant performance, let's specific to introduce the next: high-temperature magnet magnet manufacturer is introduced: the performance of high temperature resistance of magnets to magnet magnetization reverse magnetic field strength required for zero, we call it intrinsic coercive force. Intrinsic coercive force is measured magnet demagnetization resistance of a physical quantity, if the additional magnetic field is equal to the intrinsic coercive force magnets, magnet magnetic will basically eliminated. Summary of Hcj will decrease with the increase of temperature and so need to work in high temperature environment should choose high grade with Hcj. Will be a magnet magnetization to technology by external magnetic field in a closed environment after saturated undo the external magnetic field, the magnetic induction intensity of magnet performance we call residual magnetism. It said magnet can provide maximum flux values. Visible from the demagnetization curve, it corresponds to the air gap is zero, so the magnets in the practical magnet magnetic circuit of magnetic induction intensity is less than the residual magnetism. Ndfeb is now found in Br the highest practical permanent magnetic material. Professional magnet manufacturer: dongguan magnet products co. , LTD/magnet products co. , LTD.
