摘要： An electric current perturbation probe includes at least one driver coil and at least one receiver. The at least one driver coil produces an omni-directional magnetic field. The at least one receiver is decoupled from the omni-directional magnetic field. In one example, the at least one driver coil includes a first driver coil that defines a first effective coil axis which is positioned orthogonally to a second effective coil axis of a second driver coil. The first driver coil is provided with a first electrical excitation signal which is phase shifted by 90 degrees from a second electrical excitation signal used to drive the second driver coil.
