What effect does the rotational/torque force have on an elongated ferromagnetic object?

The rotational or torque force acting on an elongated ferromagnetic object in a magnetic field predominantly results in the alignment of the object with the direction of the magnetic field. Ferromagnetic materials, such as iron, have magnetic domains that can be influenced by external magnetic fields.

When subjected to a strong magnetic field, the torque exerted on the elongated ferromagnetic object tends to cause its magnetic moments to rotate and align parallel to the field. This alignment minimizes the potential energy of the object within the magnetic field, making it thermodynamically favorable for the object to orient itself along the field lines. As a result, you see not repulsion from the field, nor does the object remain stationary or experience an increase in mass. This alignment is crucial in magnetic resonance imaging (MRI) and other applications involving magnetic fields and ferromagnetic materials, helping to ensure safety and proper functioning of equipment.
