Which MD?

An usual MD should be immune against the earths magnetic field.
The soil and the metallic minerals of the bedrock for shure will influnce the earths magneticfield alot.
And depending on the minerals some or many of the metal molecules are aligning with this field.
Perhaps this is the reason why an usual metal-detector destroys the very weak "LRL phenomenon signal". It demagnetized the ground or soil at an area of its radiated MDs detection field range (perhaps up to 5 meter!).

Yes I am talking about the soil and the metallic minerals of the bedrock making it difficult for your metal detector
