Which of the following is/are true? Check all that apply.     The field lines move from the north pole of the one to toward the south pole of the other magnet.   There is a repulsive force between the north pole of the one and the south pole of the other.   There is an attractive force between the north pole of the one and the south pole of the other.   The field lines move from the south pole of the one to toward the north pole of the other magnet.
