An infinitely long wire lying along z axis cames a current 1 flowing towards positive z direction There is no other current consider a circle in x y plane with centre at 2 meter 0 0 and radius 1 meter Divide the circle in small segments and let de denote the length of a small segment in anticlockwise direction as shown Pol Im 2 2 0 0 Rd7 Consider two points A 3 0 0 and B 2 1 0 on the given circle The path integral B de of the total magnetic field g along the perimeter of the given circle from A to B is 78 x
