Torque from magnetic field

Electricity and Magnetism Level 2

A rectangular conducting wire \(PQRS\) with current intensity \(I\) is fixed on the \(xy\)-plane where a uniform magnetic field with magnetic intensity \(B\) exists, as above. The direction of the magnetic field is \(+x\) direction as indicated by the green arrow. What is the magnitude of the torque on the conducting wire by the magnetic field?
