Are cell phones afraid of magnets?

The impact of magnets on mobile phones

1. The mobile phone itself contains magnets, such as speakers, vibrating motors and flips, all of which are made of magnets. The external effect of magnets is a static magnetic field, which is not alternating and therefore does not produce an electromagnetic field.

2. The mobile phone circuit is shielded, but it only shields the electromagnetic field and has little effect on the static magnetic field. Other household appliances and magnetic magnets are not good or accurate to assemble. There are too many magnets in electrical devices. Magnets have an effect on magnetic recording materials.

3. Another aspect is that the magnetic field will interfere with the signal (electromagnetic wave). When you talk on the phone, you will not be able to hear the sound. the other part clearly due to the influence of the magnetic field.

Detailed information

Magnet

The composition of magnets consists of iron, cobalt, nickel and other atoms. The internal structure of the. atoms are relatively special, they themselves have a magnetic moment. Magnets can generate a magnetic field and have the property of attracting ferromagnetic substances such as iron, nickel, cobalt and other metals.

Magnet Types: Shape Magnets: Square Magnets, Tile Shape Magnets, Special Shape Magnets, Cylindrical Magnets, Ring Magnets, Disc Magnets, Bar Magnets, Backing Magnets, Magnets Attribute: Samarium Cobalt Magnets, Neodymium Magnets Iron-Boron Magnets (Strong Magnets), Ferrite Magnets, Alnico Magnets, Iron-Chromium-Cobalt Magnets.

Industrial magnets: magnetic components, motor magnets, rubber magnets, plastic magnets, etc. Magnets are divided into permanent magnets and soft magnets. LovesPermanent nts are added with strong magnetism to align the spin of the magnetic material and the angular momentum of electrons in a fixed direction is added with electricity.

Lithium iron phosphate battery can drive a permanent magnet synchronous motor. As the name suggests, the permanent magnet synchronous motor magnetic field uses a permanent magnet synchronous motor. magnets. Using this magnetism causes the rotor to move. Its advantage is that its energy efficiency is relatively high and it consumes less electrical energy, because the magnetic force generation process does not consume any electrical energy. However, its disadvantage is that the magnetic field of the permanent magnet is limited. cannot be increased without limit, its maximum power will be limited to a certain extent.
