What is the force between magnets

1. If you can't earn millions of yuan from his platform, you have already lost money, but it's nothing. Maybe your ID card photos have been sold hundreds of times. It doesn't matter. You can't do anything!

2. Etc can't go. In addition, there is a light on the entrance. Green light can go, red light can't go.

3. There are four basic interactions in nature. The interaction between magnets belongs to electromagnetic interaction, and the interaction between molecules belongs to gravitational interaction

Let the air gap magnetic density BG, magnetic field strength Hg, air gap area Ag and air gap length LG, then the attractive force F is:

F = BG * Hg * Ag / 2

that is, the magnetic force between the magnet and the armature is proportional to the air gap magnetic density, magnetic field strength and air gap area. See the following

for details

5. This is a very complex problem, so I won't mention it before high school, even college physics doesn't have it (college physics only has the calculation method of magnetic field generated by current, but magnet doesn't), unless it is a related major.. This is related to some properties of the magnet itself, the shape of the magnet, the magnetic medium in the middle (whether there is ferromagnetic material in the middle), and whether there is magnetization. There may be some empirical formulas for magnets with fixed shape and strength
I only know how to calculate the torque of the motor. As for me, I think it's difficult to calculate the torque of the motor for non related majors. It's more complicated because only very close can there be a force. If it's very close, it's necessary to carry out triple integral calculation according to the shape. It's very troublesome, and it's even more difficult to calculate if the shape is irregular....

6. In my opinion, yes, because the magnetic field of magnet a is ba = 1 / C * C (VA * EA), C is the speed of light, VA is the speed of electrons in the magnet, EA is the electric field intensity generated by the electrons around, and the magnetic field of magnet B is BB = 1 / C * C (VB * EB), the parameter meaning is the same as above, so using Lorentz force F = b * V, the force of magnet a on magnet B is fa = Ba * VB, and the force of magnet B on magnet a is FB = BB * VA, Therefore, their common force is FA + FB;

For a middle end 1060 graphics card host platform, the power rating is recommended to be between 400-500w. If the graphics card and CPU do not support overclocking, the power can be lower, 450W. But if both CPU and graphics card support overclocking, the power supply should be as large as possible, and the rated power supply above 500W is more appropriate

according to the public data of 1060 graphics card, the TDP of 1060 is 120W, and the external power supply uses 6pin. The setting difference in frequency and other aspects will also affect the power consumption level

The full load power consumption of

1060 graphics card platform is 203w, and the no-load power consumption is only 61W. The output voltage of the power supply in the high load state does not fluctuate greatly. When installing the computer, only need to cooperate with the rated power is basically above 400W

extended data

when installing a graphics card, you can power off the motherboard, open the chassis, find the PCI-E x16 interface (graphics card slot, now all graphics cards are PCI-E x16 type), and insert the graphics card vertically to the golden finger position on the graphics card slot, and insert it completely (subject to invisible)

after the card is plugged in, the card will be buckled. The interface of the card with external power supply should be connected to the power supply side. Connect the card with the display. After the display is turned on, download the driver from the official website. After the driver is installed, the performance of the card can be used

how much power a computer host needs to buy depends on the power consumption of the graphics card and CPU, because these two accessories are the most core and the most power consuming components, while the power consumption of hard disk, memory, motherboard and other hardware is not high, which is less than 100W

8. The power consumption of gtx1060 is only 120W. Like gtx960, 6pin power supply is sufficient. The power supply is recommended to be above 400W. The last 450 was a little bit safe
if you still consider upgrading the configuration in the future, it's best to go directly to 650

9. Above 400 W is enough. Generally more than 450 to have enough graphics power plug, so buy about 500, not too cheap

10. HTTP is the hypertext transfer protocol, s is the abbreviation of safe, which means that the network has passed the security verification. Without s, it means that there is no security verification, but it does not mean that it is not secure

HTTP (Hypertext Transfer Protocol) is the most widely used network protocol on the Internet. All www files must comply with this standard

HTTPS (full name: Hyper Text Transfer Protocol over secure socket layer) is an HTTP channel aiming at security, which is simply a secure version of HTTP. But there are still some defects: cookies and query strings may be stolen: hackers can register an account first, find the cookie, and see the expression of the value. Then, change the cookie to hijack someone else's session ID. As for the query string, it can be disclosed in a similar way

the beginning of HTTP refers to ordinary web pages, while the beginning of HTTPS refers to the use of secure encryption technology, similar to SSL VPN technology, and some often need account authentication to access< br />
