Abstract: The invention relates to a method and current measuring arrangement for measuring electric current flowing in an individual electrode in an electrolysis system. The electrolysis system comprises a plurality of interleaved electrodes (1, 2), cathodes (1) and anodes (2), arranged in an electrolysis cell (3) and immersed in electrolyte, said electrolysis system having a busbar (4) disposed on a separating cell wall (5) between each of the two adjacent cells to conduct electric current to the electrodes via a contact point (6) between the busbar and a hanger bar (7) of the electrode, and the current sensing arrangement comprises a magnetic field sensing means (8; 81, 82; 10) for measuring the magnetic field induced by said current. The magnetic field sensing means (8; 81, 82; 10) are arranged to sense the magnetic field substantially at the level of the contact point (6).
