Older electronic devices such as CRT monitors and televisions are susceptible to magnetic fields. For example, when you place a strong magnet near a TV, you may find that the TV screen may be distorted. So will magnets have a similar effect on smartphones? Will a magnet destroy your smartphone? Let’s find out.
The truth is that magnets do affect some functions of mobile phones, provided that the magnets have very strong magnetism. In fact, there are magnets inside the phone itself to achieve some functions, such as wireless charging, which will be affected by super magnets. In addition, sensors inside the phone, such as the digital compass, can also be affected by the magnet, causing errors in the display.
However, magnets with less magnetism, such as small magnetic blocks on the holster of mobile phones, magnetic mobile phone holders, etc., generally do not affect the functions of mobile phones.
The mobile phone holsters launched by many mobile phone brands such as Samsung, Apple, Xiaomi, etc. are equipped with magnets. When the holster is buckled, the mobile phone screen becomes black. When the holster is opened, the mobile phone screen becomes bright.
It can be seen from this that mobile phone manufacturers have also proved through experiments that magnets with relatively small magnetism have no effect on circuit boards, GSM signals, and GPS navigation signals of smartphones.
As for the influence of magnetic mobile phone holder on mobile phones, Foxconn’s Professional Mobile Phone Product Testing Laboratory (FIH) also conducts special tests on the antenna signal, call quality, and electronic compass function of mobile phones.
The test on the antenna signal indicates that the magnet has no significant effect on the cell phone signal. The results of call quality tests also show that magnets have no visible effect on phone calls. The only thing affected by the magnet is the compass pointer. Due to the influence of the magnet, the surrounding magnetic field changes, the compass pointer needs recalibration, after which it can be used normally.
Before using a magnetic phone holder, you need to attach an iron sheet (magnetic disc) to the phone because the magnetic force of the holder is not strong enough to directly hold the phone. The magnetic disc is similar to a magnetic horn. The magnet in the horn is equipped with an iron shell to prevent leakage of the magnetic field. The magnetic field of the magnet will not leak outside the horn, forming a closed magnetic field.
So, remember, only magnets with strong magnetism will have a greater impact on mobile phones, such as industrial magnets. In addition, if you often go to factories having strong magnetic devices, you also need to pay attention to the influence of magnets on your smartphones.
