I think not what is wireless charger Wireless charger refers to the charger that does not need to be connected to the terminal device that needs to be charged without the traditional charging power cord, 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 the connection of the charging base station and equipmentThe bridge.
According to 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.
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.
Within a distance (0.1 to 2 cm) the magnet needs to get him spinning. Wrap a coil around the magnet block. Well, it's just a generator. I've got a circuit here. Take a look. It can be done. The farthest (distance) is 4 cm. It's very inefficient. However, you can bring 10 LED highlights in close range. You can also go to Baidu ZVS.There are no magnets in the wireless charger. If you place an energized wire on a magnetic compass, you can see that these currents also produce a magnetic field. If you use a moving magnet instead of an alternating current wire, you're ready. Variation in wireThe current creates a changing magnetic field. The changing magnetic field creates an electric current in the other coil. The more loops you create, the stronger the effect.
The working principle of the wireless charger is mainly induced by magnets. When we place the phone in the inductive area of the wireless charger, the magnetic field generated by the magnet will generate an inductive current inside the phone. This current creates a voltage through the phone's electrical system, which charges the phone. Unlike wired chargers, wireless chargers transmit energy through magnetic fields rather than wires or cables. The key to this working principle is the establishment of magnetic fields.
2, magnets do affect the phone, but must be rightStrong magnetism will affect some of the functions of the 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.
3, have an impact. Generally, the magnet with small magnetic will not affect the function of the mobile phone, and the magnet with very strong magnetic will have an impact on some functions of the mobile phone. Magnets have an impact on mobile phone screens, mobile phone speakers, handsets, microphones, mobile phone electronic components, mobile phone antennas, etc. There are magnets inside the phone, and strong magnets can affect wireless chargingThe sensor inside the mobile phone will be affected by the magnet display error.
4, mobile phones can indeed be affected by magnets, especially when they encounter strong magnets. Usually, magnets with smaller magnetic properties have little effect on the normal use of mobile phones, but strong magnetic magnets may interfere with specific parts of mobile phones. Mobile phone screens, speakers, phones, microphones, and electronic components, such as those on circuit boards, can all be affected by the magnetic field of the magnet.
1, 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, there may be problems. In fact, the phone itself has magnets inside, to achieve some functions, such as wireless charging, will be affected by strong magnets.
2, the magnetic guide is better, the iron sheet is 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.
3, this is because if the magnetic sheet is too thin 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.
4, in fact, the mobile phone itself has magnets, to achieve some functions, such as wireless charging, will be affected by strong magnets. 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. Magnetic smaller magnet on the lineBoard GSM signal and GPS navigation signal have no effect.
5, you can add. iPhone EXsMAX wireless charge can be added to the magnetic disc, because iPhone ExsMAX supports magesafe, and magesafe contains the magnetic disc, which just supports the wireless charging of iPhone, so iPhone ExsMAX wireless charge can be added to the magnetic disc.
