About the ELF EMF/EMR Blocking Mu-Metal

The ELF EMF/EMR Blocking Mu-Metal Foil is a cheap why to block and divert ELF(Extreme Low Frequency) EMF/EMR(Electromagnetic Fields/Electromagnetic Radiation). It comes in the shape of foils (rolls) and it is thin, flexible and light weight , so it can be sent via the post office services. ELF is very hard to block and the ELF EMF/EMR Blocking Mu-Metal Foil  was specially designed to do so with 6 layers or different metals. In case of small ELF sources one layer of ELF EMF/EMR Blocking Mu-Metal Foil will be sufficient, in case of large sources (high levels of ELF) 2 or several layers of ELF EMF/EMR Blocking Mu-Metal Foil will be needed (in all cases a single layer will improve the condition and reduce the ELF levels to some extent).
  • Composition: Polyester, Co69, Fe4, Mo4, Nb1, Si16, B7
  • Weight: 265 g/m²; Material thickness: 0.1 mm
  • Thickness: 0.12mm
  • Roll Width: 45 cm 
  • Colors: Silver
  • Magnetic flux density, B800 (DC H=800A/m) : 1.23 T
  • Maximum permeability, μmax(DC): 70000
  • Operating temperature range: -40~+80 ℃ 
  • Grounding: may be required for better performance.

In order to block ELF EMF/EMR fields efficiently either the ELF source should be completely covered or the ELF blocking material should be applied to create a large  blocking surface (since ELF magnetic fields tends to work their way around obstetrical).

For example in a case of an Electric meter and fuse box (in Red color) that emit high levels of ELF, the ELF protection(in silver color) should be applied on most of the wall. The only way to know how big the protection should be is to use an ELF EMF/EMR meter before, during and after the protection is applied. If after the installation of the  ELF EMF/EMR bocking protection there is still ELF coming from the side of the ELF EMF/EMR protection you need to put more ELF EMF/EMR protection on the sides (Left, Right, Up and Down). If there is still ELF EMF/EMR coming via the center of the ELF EMF/EMR protection you will need an additional layer of ELF  EMF/EMR protection
