Does the torque on planar current loop in a magnetic field change when its shape is changed without changing its geometrical area.

Assertion: In electric circuits, wires carrying currents in opposite directions are often twised together. Reason: If the wires are not twisted together, the combination of the wires formes a current loop, the magnetic field generated by the loop might affect adjacent circuits of components.
