An improved corrosion-resistant magnetic influence minesweeping cable is provided. The cable produces a magnetic field that simulates a ship's magnetic signature as the ship passes through the sea. It has an outer anode conductor made of titanium-clad copper with mixed metal oxide at its aft end, an outer cathode conductor made of nickel-clad copper at its forward end, an inner conductor made of aluminum that runs the length of the cable, and a steel core strength member that also runs the length of the cable. The outer anode conductor is in electrical contact with the inner conductor. The outer cathode conductor is insulated from the inner conductor. The outer cathode conductor and the inner conductor can be connected to an electrical power source onboard a towing vessel.
