has no effect. The iPhone 12 magnetic wireless charge can be simply understood as adding a circle of magnets on the basis of the original wireless charge, and through the attraction of the magnets, the phone and the wireless charger are accurately positioned and paired, thus entering a more efficient wireless charging state. Magnetic wireless charging technology is not the first time in Apple devices, such as Apple Watch, Apple Pencil and other products are used in this way for wireless charging.
Apple mobile phone is not recommended to use magnetic charging, because this charging method is comparedSlow, and may cause damage to the battery. The magnetic function will produce a large number of times of strong coupling inductive charging in a confined space, and a lot of heat will be generated in the process of magnetic resonance coupling, high temperature is harmful to lithium batteries, and long-term high temperature will reduce battery life.
Although the magnetic phone case provides a convenient adsorption function for the mobile phone, it still has a certain impact on the mobile phone. The magnet in the phone case will interfere with the signal transmission of the phone. Although modern mobile phones have a strong signal reception, this interference is not completely harmless. If you use a magnetic phone case for a long time, the phone signal may be connectedThe result is a certain effect, especially in a weak signal environment.
Magnetic charging is not recommended for iPhone. Magnetic charging is relatively slow, will have a certain damage to the battery, magnetic function usually brings a large number of times in the confined space of strong coupling inductive charging, and in the magnetic resonance coupling process there is a lot of heat dissipation, high temperature for lithium batteries is fatal injury, in a short distance there is a lot of heat release, long-term high temperature state will damage the battery.
Most of the wireless charging applied on mobile phones is non-contact induction charging, and the magnetic charging led by Magsafe onlyJust to better align the charging coil, essentially harmless to the phone battery. However, the magnetic function usually brings a large number of strongly coupled inductive charging in a confined space, and there is a lot of heat dissipation in the process of magnetic resonance coupling, and high temperature is fatal for lithium batteries.
1, then @ charging head network exposed the magnetic module inside the iPhone12 body, the circular module on the ringI wound 36 magnets. Just two days before the press, @charging head network exposed the official magnetic protection shell of the iPhone12, which also has 36 magnets inside. From design drawings to physical components, the iPhone's magnetic function is a real hammer.
2, so in order to protect your magnetic card, so do not put the iPhone12 and some magnetic cards together. It's true that the iPhone12 degausses cards, but it's a small part of it.
3. However, the negative impact of this incident on Apple did not dissipate when the iPhone12 seriesThe column will be exposed to negative news that will degausse. However, Apple executive Kaiann Drance said that the possibility of demagnetization caused by the iPhone12 series is relatively small, so you do not need to worry too much, if you are really worried about the demagnetization of the card, you can buy Apple's new anti-demagnetization card pack, and Apple's card pack has also been sold on the official website.
4, Conclusion: The magnet structure of the iPhone 12 magnetic wireless charger was exposed, showing its innovative design, taking into account the NFC function, wireless charging and NFC use do not affect each other. Here is a more detailed introduction:2, in the field of computer technology, magnets are used to make hard disk drive read and write heads, by magnetizing to store and read data. In addition, magnetic tape is also a tool that uses the magnetism of magnets to store large amounts of data. The magnetism of magnets plays a key role in motors and generators. A motor generates a rotating force through the interaction of a current and a magnetic field, while a generator uses the rotation of a magnetic field and a coil to generate a current.
3. Geomagnetic changes can be used to explore mineral deposits. Since all substances have strong or weak magnetism, if they gather together to form a deposit, then it must be nearThe geomagnetic field in the region interferes, which makes the geomagnetic field appear abnormal.
Hello, about whether magnets will be used in the wireless charger. First of all, you must understand the principle of wireless charging, that is, electromagnetic induction, through the magnetic flux between the two coils is constantly changing, to transfer energy, and electromagnetic induction in order to make the coil magnet more concentrated, usually the core of these materials with large permeability to reduce energy loss, therefore, wireless charger inside do not need to use magnets.
The current generated by this induction can be used to charge a mobile phone. The charging efficiency of the wireless charger depends on the setting of the magnet and coilAnd how well the phone matches the charger. If the match between the magnet and the coil is not good, or the size of the phone and the charger do not match, then the charging efficiency will be reduced, or even unable to charge.
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. The varying currents in the wires create varying magnetic fields. The changing magnetic field creates an electric current in the other coil. The more loops you create, the stronger the effect.
electromagnetic induction wireless charging, when the current of the power supply through the coil (wireless charger's power supply coil) will generate a magnetic field, other unenergized coil (mobile phone side of the electric coil) close to the magnetic field will generate current, charging the mobile phone. The advantages of wireless charging safety: no power contact design, can avoid the danger of electric shock.
1, wireless charging methods include electromagnetic induction, magnetic resonance, electric fieldCoupling and radio wave transmission, wireless charging of mobile phones mostly uses the principle of electromagnetic induction. Electromagnetic induction wireless charging, when the current of the power supply through the coil (wireless charger's power supply coil) will generate a magnetic field, other unenergized coil (mobile phone side of the electric coil) close to the magnetic field will generate current, charging the mobile phone.
2, wireless charging principle: electromagnetic induction. The charging base and the mobile phone terminal have built-in coils respectively. When the two are close, the coil generates a certain current in the mobile phone receiving coil based on a certain frequency of alternating current through electromagnetic induction, thereby transferring the point energy from the originating endAt the receiving end, power is supplied to the phone from the charging seat. Magnetic resonance.
3, wireless charging system mainly uses the principle of electromagnetic induction. 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 a bridge connecting the charging base station and equipment.
4, electromagnetic induction type: The fundamental principle is to use the principle of electromagnetic induction, similar to a transformer, the primary coil of a certain frequency of alternating current, through the electromagnetic induction in the secondA certain current is generated in the stage coil, thereby transferring energy from the transmission end to the receiving end. The conversion efficiency is high, the cost is cheap, but the transmission distance is short, and it is easy to be affected by the placement.
