Part of the field change recorded is due to distortion of the Earth’s field. The steel in the cylinder has a high permeability, so magnetic field flux lines are attracted to run along the cylinder rather than through the air next to it. Therefore the direction of the Earth’s field affects the field changes made by the cylinder.
