Zusammenfassung:PROBLEM TO BE SOLVED: To provide a current converter capable of measuring a very weak direct and alternating electric current.SOLUTION: The current converter comprises a head 40 having at least two ferromagnetic cores 46, 47 surrounding a cable 45. The ferromagnetic cores 46, 47 have air gaps G1, G2. Hall devices 1, 28 are installed in the air gaps G1, G2. The ferromagnetic cores 46, 47 are positioned almost in parallel with each other at a prescribed interval from each other along an axis 50 and made to rotate around the axis 50 at a prescribed rotation angle against each other so that the air gaps G1, G2 are located at different angles.
