Abstract: A combination flux loop and B-dot probe comprising a single mineral insulated cable having an outer sheath of, e.g., stainless steel or the like, and three (3) conductors positioned within the sheath and embedded in a mineral insulator such as, e.g., MgO. One of the conductors forms a flux loop having a single loop and second and third conductors forming a B-dot probe comprises a single wire having a double loop. The combination probe is configured to prevent twisting of the conductors along a curved bend as the combined probe is fashioned into a curved shape. To prevent twisting, the conductors may be formed as ribbon wires having a generally flat, rectangular shaped cross-section and/or the sheath may have a generally oval or rectangular shaped cross-section.
