Repulsion force systems and methods for metal fish retrieval

A system for fishing a metal object from a subterranean well, the system including:

• a fishing tool with housing located within a well string of the subterranean well, the housing being an elongated member having an internal bore;
• a first electromagnetic assembly located within the internal bore of the housing and in contact with the metal object;
• and
• a second electromagnetic assembly located at an outer diameter surface of the housing, the second electromagnetic assembly being moveable between a contracted position where the second electromagnetic assembly is spaced apart from the well string and an extended position where the second electromagnetic assembly extends outward from the housing and is in contact with the well string;
• where
• the first electromagnetic assembly is operable to generate a first magnetic force with an adjustable magnitude and magnetize the metal object;
• and
• the second electromagnetic assembly is operable to generate a second magnetic force with an adjustable magnitude and magnetize the well string, the first magnetic force and the second magnetic force having a same magnetic polarity.
