We'll use the right-hand thumb rule to determine the direction of the magnetic field around the section of the loop shown. The thumb points in the direction of the magnetic field while fingers curl in the direction of the current in the loop.
Magnetic field lines start from the north pole of the magnet and enter into the south pole of the magnet.
The south pole of a bar magnet is brought toward a current-carrying loop of wire, as shown below. Does the magnet: Attract/Repel/Have no effect on the loop? Explain.
