Today to share the knowledge of how to wireless charge without the iron ring, which will also explain the wireless charge without the magnetic shell, if you happen to solve the problem you are now facing, don't forget to pay attention to the site, start now!
< ul>The principle of wireless charging is actually very simple, in fact, electromagnetic induction, a changing magnetic field can produce an electric field, and a changing electric field can produce a magnetic field. In high school textbooks, Faraday taught us about this "electromagnetic mutual.The truth of life. The charging seat and the mobile phone each have a coil, the charging seat is called the main coil, and the mobile phone is called the secondary coil.
Wireless charging principle is mainly electromagnetic induction and wireless electromagnetic wave technology. The principle of electromagnetic induction is the basis of wireless charging. Electromagnetic induction occurs when a magnetic field is generated between a charger and a mobile device. The alternating current generated at the charger end will create eddy currents in the magnetic field, and the receiving coil at the mobile device end will sense this eddy currents. In this way, power is transferred from the charger to the mobile device.
Electric field coupled wireless chargingThe principle is to transmit electrical energy through the induced electric field generated by the coupling of two sets of asymmetric dipoles in the vertical direction. Suitable for short distance charging, high conversion efficiency, the position can not be fixed; However, the disadvantage is that the equipment is large and the power is small. Therefore, at present, among the four wireless charging methods, electromagnetic induction wireless charging scheme is the most mature and most widely used in business.
Wireless charging technology is the use of electromagnetic induction principle, through the establishment of a magnetic field between the transmitting end and the receiving end, so that electric energy can be transferred between the two ends, so as to achieve the process of charging. At this stage, most wireless charging devices are usedQi is the standard, which mainly specifies the power and distance of wireless charging, and some big brands such as Apple and Samsung have also adopted this standard. However, there are some limitations to using wireless charging.
Wireless charging principle: wireless charging mainly uses electromagnetic induction, the charger and the electrical device to transmit energy by magnetic field, and the two are not connected by wires, so the charger and the electrical device can be no conductive contact exposed. Wireless charging technology comes from radio energy transmission technology, which can be divided into two ways: low-power wireless charging and high-power wireless charging.
electromagnetic inductionCao), hate Guan Yu (Guan Yu) not Zhang Fei (Zhang Fei) two boats racing, Lu speed (Lu Su) as fast as the sail (climb Kuai) hundred pipe contend, Di Qing (Di Qing) than Xiao and (Xiao He) answer two apes broken wood deep in the mountains, the little monkey also dare to saw (sentence).

Luo Guo Mountain -- money (Before) tight, metaphorical lack of money dog chasing ducks -- quack.
There is also a homophonic allegorical, which is in the previous categoryOn the basis of the type added harmonic elements. For example: nephew playing lanterns - as usual (uncle) Confucius moving - net is to lose (book) fire flagpole - sigh (charcoal) cesspar closed knife - Wen (smell) can not, Wu (cover) can not.

Careless loss of Jingzhou: metaphor due to negligence and lead to failure or loss, there are careless, pride to despise the enemy.

Guan Yu lost Jingzhou - Pride must fall source: "Three Kingdoms" sentence: Du Yuesheng has a sentence hanging on the mouth of the words: careful to the world, careless lost Jingzhou.
