Hi all..

Prehaps somebody could help me working out the following, I`ve done it
myself but I keep getting results that just don`t look right.

There is a coil that is producing a magnetic field strength(H) of 25.8
dBuA/m at 10 m. I make this 0.000381 A/m. I want to then convert this to
flux density(B) in Gauss. So as I understand it the formula is.

Flux Density(B) = Field Strength(H) x Permability of Material.

I work this out using the permability of air and don`t seem to get the right
answer.


In case anybody is wondering i`m trying to work out if it`s possible to
detect a certain coil at 10m using a hall effect sensor.


Any help appreciated.
