If the magnet begins to move, electromagnetic induction will result in the coil of wire exerting a force on the magnet. As the magnet moves to the left, in which direction will the resulting force on the magnet act? O upward O to the left downward O to the right lf, instead, the magnet moves to the right, in which direction will the resulting force on the magnet act? O to the right to the left C upward downward Previous X Give Up & View solution Check Answer Next Exit B Hint
