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.
2, the principle of wireless charging technology is "magnetic electricity", simply put, through the charging device and mobile phone equipment installed on the two "magnetic equipment.They interact and form an electric current. At present, products supporting wireless charging have appeared in mobile phones, electric vehicles, smart furniture and other fields. Among them, in the mobile phone industry, the "Qi standard" is the most common, and Qi labels are often used in the packaging of many mobile phones and wireless chargers.
3, the scientific and technological charm behind the magnetic charging treasure comes from its unique magnetic principle. Magnetic charging uses the gravitational force of the positive and negative electrodes of the magnet, as the magic of the magnetic force, to easily achieve wireless power transmission, so that the connection between the mobile phone and the charging bank is no longer a tedious insertion and removal operation, but a natural adsorption like the magnetic force. <4, wireless charging technology is derived from radio energy transmission technology, small power wireless charging often uses electromagnetic induction, such as the Qi method of mobile phone charging, but ZTE's electric vehicle wireless charging method uses induction, high-power wireless charging often uses resonance. The power supply device transmits energy to the electrical device, which uses the received energy to charge the battery and at the same time for its own operation.
5, the working principle of magnetic charging: magnetic charging technology is mainly the use of magnet male and female to absorb to achieve the effect of charging. The design of this magnetic charger is very convenient, just to turn the phoneThe back is aligned with the charger, and the magnetic force between the two causes them to automatically stick together. In this way, the user does not need to accurately align or arduously insert the cable, just put the phone gently close to the charger, and it will automatically adsorb and start charging.
6, generally seen wireless charging, the use of the "current magnetic effect" and "electromagnetic induction" principle. In 1819, Danish scientist Elster observed that if there is an electric current on a wire, a magnetic field will be generated around it, which can deflect the north finger. Later, it was found that when the wire was looped or even wound into a coil, the magnetic field would be stronger and more concentrated,What is the role of potentiomagnetic
The purple circle inside the phone case is the magnetic effect can be used to charge. The new Magsafe magnetic wireless charging technology equipped with iPhone12 can be simply understood as adding a circle of magnets on the basis of the original wireless charging technology. Through the attraction of magnets, the mobile phone and the wireless charger are accurately positioned and paired, while effectively avoiding displacement due to vibration, so that the mobile phone is in a more efficient wireless charging state. Supports up to 15W power.
This phenomenon is called "magnetic resonance", which is used for wireless charging, which can make the charging distance up toBy a few meters, efficiency is also improved. The only difficulty is to adjust the two circuits to the exact same frequency and maintain it for some time.
In fact, in order to make the wireless charger more accurate positioning, to prevent wireless charging, the coil between the phone and the charger can not be on, resulting in normal charging, Apple is trying to achieve the curve overtaking through this function. From previous images of the phone's case containing a metal ring and two metal contacts, we can assume that this ring of magnets is used to locate the magnetic charger, which is common on the Apple Watch.
SendThe end coil is connected to the wired power supply to generate electromagnetic signal, and the receiving coil senses the electromagnetic signal of the sending end to generate current to charge the battery; The magnetic field strength of the coil can be enhanced by attaching a magnetic separator to the antenna at the transmitting end, and the magnetic convergence effect is higher. A magnetic separator is placed on the receiving antenna to prevent the attenuation interference of the metal conductor on the magnetic field, play the role of metal isolation, prevent energy waste, and improve the charging efficiency.
Mobile phone wireless magnet principle: The induction magnetic flux generated between a wireless charging board and the induction magnet on the mobile phone is converted into an electric power for current transmission.
The Apple 12 has a magnetic function. According to the inquiry smart home network, the Apple 12 has a magnetic function. Apple 12 series mobile phones support magnetic wireless wireless charging, you need to use MagSafe wireless charging or Qi wireless charging.
iPhone12 series. In order to improve the charging experience of mobile phones, Apple introduced the Magsafe magnetic wireless charging function from the iPhone12 series. This design eliminates the need for user alignmentPort, just put the charger close to the phone, it will automatically adsorb together to start charging.
No. Not only the Iphone14 can use magnetic, the Iphone113 series can use magnetic, the Iphone113 has a magnetic function.
With magnetic function. According to the information on Apple's official website, the iPhone12 supports MagSafe magnetic technology, which can connect chargers and other accessories through magnetic magnets, and can use MagSafe wireless charging or Qi wireless charging.
Yes, the Apple 12 supports magnetic wirelessCharge it. Magnetic Wireless charging for Apple 12 The iPhone 12 has magnetic wireless charging. This is a new technology introduced by Apple in the iPhone 12 series to improve the experience and efficiency of wireless charging. The magnetic wireless charging function makes the mobile phone and the wireless charger more closely fit together through the magnetic technology, so as to achieve more efficient and stable wireless charging.
