Two bar magnets are placed end to end with a small gap between them. The north pole of one faces the south pole of the other. What do the field lines in the gap look like?
They run across the gap from the north pole to the south pole
They run across the gap from the south pole to the north pole
They curve away from the gap, so there are no lines in the gap
They form closed circles inside the gap between the two poles
