degaussing magnet

Product Introduction The active Magnet sensor detects the change of magnetic field, and when the magnetic flux object approaches the active magnet, the active magnet output positive pulse, and the active magnet output voltage is 0V when the magnetic flux object is away from the active

How is the degaussing scanner used for supermarket cash registers? Let's start with the electronic product anti-theft system:Electronic Article Surveillance, also known as the electronic goods anti-theft system, is one of the product security measures widely used in the large retail industry. The EAS system consists of three parts: the sensor, the deactivator, and the electronic label and tag ). Electronic Tags are divided into soft tags and hard tags

In the previous blog, we mentioned the formula for calculating the position coordinates of the sensor using magnetic field strength, and the following describes how to use the smartphone to complete the magnet tracking (any device with a magnetic sensor can), here is mainly the use of Android phones.?1: Procedure steps: First put the magnet away from the phone position, and then hold the phone in t

For ordinary users, the display is very annoying to be magnetized, especially for those who do not have degaussing function of the display itself is even more troublesome. In fact, the solution is not difficult, for strong electromagnetic interference magnetization of the display, it is best to use special degaussing equipment to complete, such as degaussing rods

, affecting the magnetic field on the disk. Because electromagnetic induction is used in this process, the heat of the magnetic head is high. But the disk itself will not heat, because the permanent magnet on the disk is cold, not because of magnetic field changes and fever. However, in general, the heat produced by the head is a little cool compared with the previous two. Heat can be transmitted by radiation, so will high heat damage the permanent

by the head is a little cool compared with the previous two.Heat can be transmitted by radiation, so will high heat damage the permanent magnet on the disk? In fact, the damage is very small. The temperature of the Permanent Magnet degaussing is much higher than the normal temperature of the hard disk. Of course, if your chassis has poor heat dissipation, you ca

Open the display machine does not display, with the Multimeter electric barrier test power line input, resistance to infinity, indicating that the power cord has been open. Power-on check, found that the fuse on the circuit board has been blown, replaced with a new fuse, the boot that burns insurance. There is a high pressure inside the monitor, although it does not cause life risk, but the taste of electric shock is not easy. Therefore, in the maintenance of the monitor, in order t

change high voltage to low voltage by using a step-down transformer, which is conducive to safety and lowers your insulation requirements for the equipment. In addition, compared with DC motor, AC motor has the advantages of low cost and easy maintenance. Therefore, AC has been widely used. 20. Why can't I only measure the DC power but the AC power? A: Because the magnetic field direction of the Permanent Magnet cannot be changed, only the DC current

need to store the bookshelfBook find, put on the special cart, pull to the 3 floor of the shop, the other books will be in storage. Bookstore in the basement of the ground floor, the space is not small, but the inside of the whole, categorized storage of various books. This period of time in addition to the book store in the large flow of books, e-book now also increased the flow of books, so the bookstore temporarily applied for a warehouse storage. 2. magnetic field from the warehouse to the

mostly because the display has a magnetic field around the device to the picture tube has a magnetized effect, such as computer speakers, microphones, stereos and so on. Under normal circumstances, the computer's dedicated speakers are magnetically treated, it will not be magnetized display, but inferior speakers may have magnetic leakage phenomenon. It is common that some speakers of the side or after the face of the display has a certain magnetic effect. If you find that the display may be ma

Describe In a vast expanse of wilderness, strewn with n pieces of magnets. The properties of each magnet can be described in a five-tuple (x,y,m,p,r), where the x,y represents its coordinates, m is the mass of the magnet, p is the magnetic force, and R is the suction radius. If the distance between the magnet A and the magnet
