1.	Does the torque on planar current loop in a magnetic field change when its shape is changed without changing its geometrical area.
Answer» Torque on a planar current loop is given by `tau=niAB sin alpha`, which is independent of shape if area A is unchanged. Hence torque on a planar current loop in a magnetic field does not change when its shape is changed without changing its area.
