A square current carrying coil of edge length L.the magnetic field on the coil given by Bvector=B0y/L icap +B0x/L jcap where B0 is a positive constant.(A is area of coil). 1) If the coil is free to rotate about x axis torque on coil is given by 1/2iAB0icap 2)if the coil is free to rotate about y axis torque on the coil is given by -1/2iAB0j cap 3) resultant force on coil is zero 4)equation for torque μ vector cross B vector where μ is magnetic moment of coil is not valid on coil if any of the side is fixed as axis
