A bar magnet with N pole pointing right is placed near a circular current loop whose magnetic moment also points right. The interaction is

1. A current loop acts as a magnetic dipole; aligning moments means the loop's south pole faces the magnet's north pole. 2. Opposite poles attract in magnetic interactions. 3. The non-uniform field of the bar magnet exerts a net force on the loop. 4. The force pulls the loop toward the bar magnet, so the interaction is attractive. _Source: syllabus Physics Ch 4 "Moving Charges and Magnetism", §4.10.2_
