1, 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.
2, mobile phone wireless charging technology is completely without the use of wires, the use of magnets for mobile phone charging technology. Mobile phone wireless charging technology, derived from wireless power transmission technology, using magnetic resonance in chargingThe electric charge is transferred in the air between the device and the mobile phone, and the coil and capacitor form a resonance between the charger and the mobile phone to achieve efficient transmission of electric energy technology.

4. The current generated by this induction can be used to charge the mobile phone. The charging efficiency of the wireless charger dependsIn the design of magnets and coils and the matching degree of mobile phones and chargers. 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.
5, electromagnetic induction wireless charging: This way of charging is to use the inductive magnetic flux generated between a wireless charging board and the induction magnet on the mobile phone, and convert this magnetic force into a power for current transmission.
6, 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.
2, the cause of the failure: the wireless network card driver is disabled, the wireless network environment has changed, the router Settings have changed, the wireless network card is not correctly set, the operating system is not correctly set, the wireless router is faulty, the wireless network card is faulty.
3, common reasons: one-click optimized Settings: Older 360 browsers may turn off critical "event log" services, which can lead to limited wireless network connection. Hardware problem: The wireless network card hardware switch is not turned on, or the driver is faulty, you need to adjust accordingly.Wireless management tool conflicts: Multiple wireless management tools can cause confusion in the wireless connection, and it is necessary to clarify which tool is working.
4, xp wireless network connection can not find the solution: find the run in the start menu, open after entering services.msc and open. Then open the interface found in service (local) as the fifth from the bottom, name WirelessZeroConfiguration, and on the left click on the start this service. Then right-click the wireless network connection in the lower-right corner of your computer and click "Open Network Connection."
5, first in the computer desktop, see the wireless network icon, click the following "icon", click the icon after the wireless network connection appears, select the wireless network to connect. Here you want to enter the network key, which is the router's wireless password, enter it and click "Connect". If it is correct, it can be connected, and so on, if it is not correct, it cannot be connected.
1, make a small Tesla coil, you can use the MKPH capacitor of the induction cooker. Usually, a single pressure 1200V capacity of 0.3 micromethods. If there is no induction cooker capacitor, the ceramic capacitor seems to be a good choice. But some porcelain capacitor quality is not good, will be serious heat. In this project, I suggest that you buy 25 ceramic capacitors with a voltage of 3kV and a capacity of 10nF, five and five strings, at a cost of about 8 yuan. In this way, you can get very close to resonance.
1, connection: The corresponding rectifier and the car is as follows, red -- red, black -- red, yellow -- yellow (or white), powder -- white (or yellow), green -- green. The green line is the ground, the yellow line and the pink line are the input, the red line is the output and the black line is the sample voltage regulator. Either of the two red lines is the output, the other red line is connected to the voltage regulator, the green is the ground, and the yellow and white are the input.
2, the green line of the rectifier is grounded, the yellow line and the pink line are the input, the red line is the output, and the black line is the sampling voltage regulator. If the two red lines on the car do not separate colors, either one is the output, the other red line is connected to the voltage regulator, the green is grounded, and the yellow andWhite is the input. That is, the corresponding of the rectifier and the car is as follows, red and red, black and red, yellow and yellow (or white), powder and white (or yellow), green and green.
3, the five-wire rectifier than the four-wire rectifier has more than one sample voltage line, generally black, it is connected with the power supply line of the key door switch, that is, the key has electricity that line.
4, the red line is connected to the positive electrode of the battery, the white line and the yellow line are connected to the magneto corresponding color wiring, the green line is connected to the iron, the black line is connected to the power cord of the electric door lock, that is, after opening the key, the black line is connected to the power supply of the battery.
