Two bar magnets are placed in a line with their north poles facing each other.
Which statement describes the magnetic field lines in the gap between the two north poles?
They go straight across the gap from one north pole to the other
They curve away from each pole and do not cross in the gap
They form closed circles in the middle of the gap between the poles
They go into each north pole from the middle of the gap between them
