Ferromagnetic interference in stable magnetic fields

Interference from much closer ferromagnetic parts is much stronger than the hard-iron and soft-iron. This effect can be realised in Figure, as stainless-steel scissor is brought near to the magnetometer. The magnetic field in x-axis sees a sharp rise to 379.45 uTesla. For this reason, magnetometer must be isolated from such materials. In developed hardware, a magnetometer is placed above the robot, isolated from a wire carrying electric current.
