摘要
Systems and methods for fishing a metal object from a subterranean well include a fishing tool with housing, the housing being an elongated member having an internal bore. A first electromagnetic assembly is located within the internal bore of the housing and a second electromagnetic assembly is located at an outer diameter surface of the housing, the second electromagnetic assembly being moveable between a contracted position and an extended position where the second electromagnetic assembly extends outward from the housing. The first electromagnetic assembly is operable to generate a first magnetic force with an adjustable magnitude. The second electromagnetic assembly is operable to generate a second magnetic force with an adjustable magnitude, the first magnetic force and the second magnetic force having a same magnetic polarity.
