As we all know, the wireless charging coil has a magnetic separator, so why to add it, do not add line? The following is to follow the Xiaobian explanation to understand why wireless charging to add magnetic separation Magnetic separator is a magnetic sheet auxiliary material of the coils at both ends of the wireless charger. It is a magnetic material sintered by constant high temperature. The common coil separator magnetic sheet is divided into the receiving end (usually soft magnetic sheet with very thin thickness) and the receiving end of the transmitting end (usually hard magnetic sheet with hard and fragile material and thickness of about 0.1~0.8mm). Wireless charging coil uses the principle of electromagnetic wave induction to charge the electronic components, the inductive coil at the sending end is connected to the wired power supply to generate electromagnetic signals, and the inductive coil at the receiving end converts the electromagnetic signals at the sending end into current to charge the battery. The main functions of the magnetic separator are as follows: An increase in the flux of the coil in the magnetic field, the greater the magnetic induction intensity of the place, the more magnetic sensing lines will separate the magnetic sheet has a higher magnetic convergence effect, through the convergence of the magnetic field in the magnetic field, the greater the magnetic induction intensity, the greater the magnetic flux, which plays the magnetic field energy of the transmitting coil to the maximum effect on the receiving end of the coil, improve the electromagnetic conversion efficiency In the magnetic field, the electromagnetic signal is prone to be absorbed and attenuated by the metal, which wastes energy and reduces the electromagnetic conversion efficiency. Affixed with a magnetic separator, the contact between the metal object and the electromagnetic signal can be effectively isolated, which reduces the attenuation of the electromagnetic signal and ultimately plays the role of blocking the magnetic field The higher the magnetic induction intensity in the magnetic field, the more heat will be generated by the charging coil. If the heat is not effectively dissipated in the circuit, it will accumulate in a certain space, which may cause damage to the electronic equipment. The heat we feel during wireless charging is thus the reason for the magnetic sheet of the coil Circuit board complete combination can increase the inductive coil contact area, can effectively disperse heat and transfer heat, reduce the heat per unit area.
