Draw lines of forces due to two bar magnets, the north pole of one facing the north pole of the other.

Solution

Properties of field lines are
Here field lines form a closed continuous loop.
The field line will emerge from the N pole and end at the S pole.
Since both the magnets are facing the same pole, so the field lines will repel each other.
The field lines will never intersect each other.
The magnetic field lines of two bar magnets, the north pole of one facing the north pole of the other, looks as shown below:
