Here it is the form of prism..and distance between DE and AH is neglibly small.
1.The direction of magnetic field at the geometric centre of three dimensional prism shaped coil will be
2. if an external magnetic field B is applied along +ve z axis then the force on the coil ABCDEFGH due to B alone will be equal to
3.If the mass of voil is m, in which direction an external magnetic field should be applied so that net normal reaction from the ground is on AH
