Can yes yes. Over a small distance (0.1 to 2 cm) the magnet needs to move him around. 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. Turn left | turn right. You can also go to Baidu ZVS.
Electromagnetic induction wireless charging: This way of charging is the use of a wireless charging board and handsThe induced magnetic flux generated between the induction magnets on the machine converts this magnetic force into an electric power for the transmission of current.
Yes. 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, materials with large permeability such as iron cores are used to reduce energy loss, so there is no need to use magnets inside the wireless charger. Some wireless chargers have a magnetic design, such as Apple's MagSafe, which uses magnets to attract the device for positioning and charging.

First cut the USB charging cable into two sections not far from the two ports. Glue the ends of the two wires with scissorsA section out of the shielding and the bottom line is generally complex green line cut off. Use hot glue to attach the magnet to the charger. Wrap the wires in the USB with tinfoil. Then wrap the wires and roll them up with copper wire. The USB cable with the copper wire rolled up is then wrapped in electrical tape.
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. And the changing magnetic field willA current is generated in the other coil. The more loops you create, the stronger the effect.
Now the wireless charging is more common magnetic resonance charging mode. The use of magnetic resonance technology principle, junior high school logistics textbooks have some knowledge, simply put: electricity generated magnetic, magnetic generated electricity! The magnetic field generated by the coil is then converted into electricity by the receiving coil, which is why this wireless charging device often carries a thick base and a "phone case".
The current generated by this induction can be used to charge a mobile phone. The charging efficiency of the wireless charger depends on the design of the magnet and coil as well as the phone andThe main difference is their charging method and scope of application. To put it simply, wireless charging treasure uses wireless charging technology, which can provide charging services for devices that support wireless charging; The magnetic charging bank is connected to the device through magnetic adsorption to provide wired or wireless charging for the device.
3, magnetic charging treasure charging efficiency is high, and cost-effective. Wireless charging bank is more convenient to use, but the charging conversion efficiency is relatively low.
4, a number of third-party magnetic charging treasure, generally support 15W and above Qi protocol wireless charging, when charging the iPhone onlyThere's 5W. Therefore, the charging power of the magnetic charging treasure is far less than that of the wired one, but there are many more scenarios for it to charge. When walking, users can stick the two devices in a piece, put them in a pocket, put them in a bag to charge, which is difficult to do with traditional wired charging banks because of their larger size.
