How to Block Cell Phone Signals With Magnetic

Mobile phone transmissions use radio waves. If you can block or delete the radio signal then the mobile phone will not work in a certain area. Magnets can provide an excellent shield for the radio waves that make up mobile communications. While many devices on the market block cell phone signals, only a few work with magnets, which protect rooms and homes.

Use Magnetic Wood Panels

Magnetic wood is one method for block cell phone signals. This is an amazing technology to deal with all mobile users.

His approach is not relevant to microwave and user alignment scenarios. This does not need the use of a signal jammer.
Magnetic particles are present in several types of wooden magnets. When an electromagnetic wave interacts with ferrite, the ferrite absorbs the wave’s magnetic component. This effectively disables the phone.

Bluetooth frequency blocking

A tree absorbing radio frequencies can be built using 4 methods.

The ferrite had only been energized previously.
Second, cider sawdust combined with ferrite powder. The wood panel was then pressed.

  1. The third method uses magnetic particles to spray the wood.
  2. The latter is a ferrite powder wood pulp mix between 2 thin wooden panels.
  • Do the Testing

When tested with a collar of listed things on a tiny antenna emitting radio waves at an ordinary 1.8 GHz frequency and a mobile GSM frequency of 900 MHz.

  • It can transmit bandwidths up to 2.5 GHz, including antenna lengths available on all wireless phone networks, primarily Bluetooth and WiFi.

4.   Using Ferrite Sandwich

Ferrite works well between thin sheets of wood. Irradiation can be obtained from sandwich microwaves having a thickness of 4 mm. The wave strength is reduced by 97%. The space on the outside of the sandwich can increase the thickness of the wood chips and enhance the drink. Here are some places you can use.

  • You can build walls and doors with wooden shields in a specific area or use a full house where mobile phones don’t work. Restaurants and movies are useful. Sensitivity is important here.
  • Many Japanese cities use radio waves on the panel. This is primarily to eliminate the problem of having wireless computer networks at home, which can cause interference if many of them are present. So if you use panels it will help to divide the building into separate pieces. This means that multiple networks can coexist.

The wooden board is useful even at premium prices.


Cell phones are more distracting than connecting to the media at the time. Excessive use is really dangerous. For example, for immoral and immoral acts used by certain individuals. It’s time to limit the use of gadgets like magnets.

Is there a way to block cell phone signals?

Although the law explicitly prohibits the use of a device to actively interfere with cell phone signals, there are no passive mobile phone blocking rules. i.e. the use of materials such as wallpaper or building materials embedded in metal parts to prevent the entry or exit of mobile phone signals.

What materials can block cell phone signals?

Non-directional materials such as wood, drywall, plastic, and glass obstruct but do not block cellular signals. Tin, copper, silver, and aluminum, among other components, can totally block signals.

Does aluminum foil block cell?

Effect. aluminum foil wrap faraday cell phone. The aluminum plate prevents the signal from reaching the mobile phone because cell phone transmissions are electronic.

What happens when you wrap your cell phone in aluminum foil?

According to Still Works, the aluminum eventually interferes, as it reaches your antenna, so there’s no call or call if the phone isn’t wrapped. Instead of blocking the cell signal, wrap some of these phones in tin foil.

Why you should wrap your key fob in aluminum foil?

However, when your vehicle doesn’t have these kinds of security measures that don’t bend your keys like the old sandwich, there are several ways to lock your key signal. Eventually, your core phobia signal is shown below, but it is not completely obstructed because the material is not that thick.
