Magnetic energy product BH: represents the magnetic energy density established by the magnet in the air gap space (the space of the two magnetic poles of the magnet), that is, the magnetostatic energy per unit volume of the air gap. Since this energy is equal to the product of Bm and Hm of the magnet, it is called the magnetic energy product. I believe that everyone understands the principle of why the magnet can absorb iron, in fact, most magnetic materials can be magnetized in the same direction to saturation, this direction is called "magnetization direction" (orientation direction).
The working principle of permanent magnets is made using Faraday's electromagnetic induction principle.

Apple 11 pro max parameters are as follows: The iPhone11 Pro Max uses a 5-inch OLED full screen, the body is made of stainless steel, and the front and back are strengthened by the double ion exchange process glass panels. The length is 158 mm, the width is 78 mm, the thickness is 1 mm, and the weight is 226 grams. Available "gold", "dark space gray", "silver", "dark green" four colors to choose from.
iPhone 11Pro max weighs 226 grams Expand your knowledge: The iPhone is an Apple Inc.) A series of mobile phones equipped with the iOS operating system launched on January 9, 2007.
Short for iPhone 11 Pro Max. The iPhone 11 Pro Max is a smartphone designed and sold by Apple Inc., one of the 13th generation iPhone series smartphones and the successor to the iPhone XS and iPhone XS Max. It was unveiled with the iPhone 11 by CEO Tim Cook at the Steve Jobs Theater on Apple Campus on September 10, 2019It will go on sale in most parts of the world on September 20, 2019.
The length of Apple 11Promax is 150mm, the body size is 150*78*1mm, the screen size is 5 inches, equipped with super retina XDR display, using HDR and original color display technology, matte texture glass with stainless steel design. The iPhone11pro max Face ID supports security verification and Apple Pay, and its A13 Bionic has a third-generation neural network engine chip.
Apple 11pro max has noise when making callsWhat's going on? It may be that the handset is in the debris, because the handset has magnetic substances, which are easy to absorb small particles containing iron components. It may be that the communication signal is not good, it is recommended to call a place with a good signal or change the operator to try. It may be that the handset and other mobile phone hardware is faulty, it is recommended to go to the regular after-sales center for processing.
The magnet has an impact on the mobile phone Will the magnet affect the wireless charging , it is recommendedDon't leave your phone with your magnet. The magnet will affect the signal of the cell phone. The magnet will affect the magnet in the handset, so that the magnet will not affect the wireless charging You can not hear clearly. Easily damaged mobile phone magnet contact mobile phone will make mobile phone scrap.
The mobile phone is placed with the magnet, and the magnet will have an effect when using the compass. However, it has no effect on other functions or internal data. The compass is affected when using the compass, because the mobile phone needs a magnetic field to determine the direction. If there is a strong external magnet, it will affectThe magnetic field of the phone. As a result, magnets can temporarily interfere with the digital compass and magnetometer in smartphones, which can cause directional misalignment.
100% matters. The harm of magnets to mobile phones is very great, such as mobile phone screen flower screen, mobile phone speaker, handset, microphone degaussing, mobile phone electronic components magnetized, mobile phone antenna magnetized, etc.). It affects the magnet in the handset and can not hear clearly (fatal injury to the handset and speaker of the phone).
Magnets have an effect on mobile phones. The reasons are as follows: Will the magnet affect the wireless charging : The danger of the magnet to the mobile phoneHarm is very big, such as mobile phone screen flower screen, mobile phone speaker, handset, microphone degaussing, mobile phone electronic components magnetized, mobile phone antenna magnetized, etc.). There are magnets in the phone itself. The external effect of the magnet is a static magnetic field, not alternating and therefore does not produce an electromagnetic field.
