A small, rigid circular loop of wire carrying a steady current lies in a plane perpendicular to the \(x\)-axis. The loop is situated in a non-uniform magnetic field whose field lines point generally in the \(+x\)-direction and diverge (spread outward) as \(x\) increases, as shown in the diagram. The magnetic dipole moment \(\vec{\mu}\) of the loop points in the \(+x\)-direction. Which of the following correctly describes the direction of the net magnetic force on the loop and provides the valid physical justification?
