Revolutionizing the wireless charging experience, Nomad base station with new magnetic alignment feature Nomad, known for its exquisite iPhone case and excellent Apple accessories, recently launched an upgraded version of the BaseStation Hub wireless charger, taking technology and convenience to a new level. One of the highlights of this charger is the introduction of the magnet design, for MagSafe-compatible iphones or accessories precisely aligned, no need to worry about finding1, wireless charging is also known as inductive charging, non-contact inductive charging, from wireless power transmission technology, is the use of near-field induction, that is, inductive coupling, by the power supply device (charger) to transmit energy to the power device, the device uses the received energy to charge the battery, and at the same time for its own operation.
2, the principle of wireless charging 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. Charger end generationThe alternating current of the mobile device will create eddy currents in the magnetic field, and the receiving coil on the mobile device will sense this eddy currents. In this way, power is transferred from the charger to the mobile device.
3, the use of electromagnetic induction principle for charging equipment, the principle is similar to the transformer, through the transmitter and receiver end set coil, transmitter coil under the action of power to send electromagnetic signals, the receiving end coil to receive electromagnetic signals and electromagnetic signals into current, so as to achieve the purpose of wireless charging.
4, the basic principle of wireless charging, is to convert the current into a magnetic field, and the magnetic field is transmitted through the airIt is converted into current and transmitted to the intelligent terminal. When the system works, the input end converts the AC mains into direct current through the full bridge rectifier circuit, or uses the 24V direct current end to supply power to the system directly. After passing through the power management module, the output direct current is converted into high-frequency alternating current through the 2M active crystal oscillator inverter to supply the primary winding.
1, can. The wireless charger works on the principle of electromagnetic induction, which transmits energy through the constantly changing magnetic flux between the two coils. In order to make the coil magnet more concentrated, the magnetic permeability such as iron core is usedThe high rate of material to reduce energy loss, so the wireless charger does not need to use magnets. Some wireless chargers have a magnetic design, such as Apple's MagSafe, which uses magnets to attract the device for positioning and charging.
2, I think what is not wireless charger Wireless charger refers to the charger that does not use the traditional charging power cord to connect to the terminal device that needs to be charged, using the latest wireless charging technology, through the use of the magnetic field generated between the coils, the magic transmission of electrical energy, inductive coupling technology will become a bridge connecting the charging base station and equipment. <3, according to the theory, this should be affected, because the principle of wireless charging is to generate a magnetic field through the power supply, and then the induction coil in the mobile phone to convert the magnetic into electricity, if there is a magnet sheet, it may complete the magnet sheet heat, may cause problems. In fact, the phone itself has magnets inside, to achieve some functions, such as wireless charging, will be affected by strong magnets.
4, wireless charging is the transmission of magnetic field energy, magnetic materials will affect the magnetic field, will block the magnetic field transmission, there is no magnetic field, there is no energy, so it will affect wireless charging.
5, the wireless charger magnet attracted to the iron plate is no problem, because it has some magnet magnetism can produce some magnetic magnet. As long as the normal charger can be guaranteed.
6, the magnet does affect the mobile phone, but it must be very strong magnetic will have an impact on some of the functions of the mobile phone. In fact, the phone itself has magnets inside, to achieve some functions, such as wireless charging, will be affected by strong magnets. In addition, the sensors inside the phone, such as the digital compass, will also be affected by the magnet display error.
1, magnetic charging is through the magnet male and female suction so that the charging cable and the jack can be connected to charge. In essence, it is still wired charging, but from plug-in to adsorption. This is very different from wireless charging, magnetic charging can not be charged without a line. Wireless charging is a technology that does exist, and the technology has been widely used in electronic devices.

Wireless charging is a technology that does exist, and the technology has been widely used in electronic devices.
3, magnetic wireless charging technology is a magnetic way to achieve wireless charging. The advantage of magnetic wireless charging technology is that the device can be firmly fixed on the magnetic base when charging and is not easy to fall off. At the same time, the magnetic base can be adjusted according to the needs of non-equipment, and the charging effect is more stable.
4, Qi wireless charging: This is a wireless charging technology based on electromagnetic induction principle. First, you need a support Qi Wireless charging standard charging base or charger. The mobile phone is placed on the charging base or charger, an electromagnetic field will be established between the mobile phone and the charging base, and the energy will be transmitted to the charging receiver of the mobile phone through the principle of electromagnetic induction, so as to achieve wireless charging of the mobile phone.
5, wireless charging is also known as inductive charging or non-contact inductive charging, based on the principle of electromagnetic induction, it is not necessary to transmit electricity to the device like the traditional wired charger, but the device that needs to be charged can be charged by contacting the wireless charging base.
Wireless charging is the transmission of magnetic field energy, magnetic materials will affect the magnetic field, will block the magnetic field transmission, there is no magnetic field, there is no energy, so it will affect wireless charging. In theory, wireless charging technology is safe and harmless to the human body, the resonance principle used by wireless charging is magnetic field resonance, which is only transmitted between coils resonating at the same frequency, and other devices cannot accept the band, in addition, the magnetic field used by wireless charging technology is itself harmless to the human body.
The magnet does affect the mobile phone, but it must be very strong magnetic to have an impact on some functions of the mobile phone. In fact, the phone itself has magnets inside, to achieve some functions, such as wireless charging, will be affected by strong magnets. There are also sensors inside the phone, such as digital RODisk, will also be affected by the magnet display error.
Drive moreWell, iron sheets are cheaper. The pilot disc is better. The magnetic guide adopts an opaque material of a primary color silver, which belongs to stainless steel products. Magnetic diskette is mainly used in mobile phone products. Iron sheets are cheaper. Iron can't be charged wirelessly. So it must be better, but the price is cheaper.
This is because if the magnetic sheet is too thin, it will cause magnetic saturation problems. If magnetic saturation occurs, the inductance of the coil will suddenly decrease, which may cause obstacles to the wireless charging process.
In fact, there are magnets inside the mobile phone itself, to achieve some functions, such as wireless charging, will be subjected to super magneticThe effect of iron. For small magnetic magnets (such as the small magnetic block on the mobile phone case, magnetic mobile phone holder, etc.) generally does not affect the function of the mobile phone. The smaller magnetic magnet has no effect on the circuit board GSM signal and GPS navigation signal.
