Consider two infinitely long wires parallel to the z axis carrying the same current I Y One wire passes through the point L with coordinates 1 1 and the other through M with coordinates 1 1 in the XY planes shown in the figure The direction of the current in both the wires is in the positive z direction a Find the value of B d along the semicircular closed path of radius 2 units shown in the figure L 1 1 M 1 1 b A third long wire carrying current and also perpendicular to the XY plane is placed at a point N with coordinates x 0 so that the magnetic field at the origin is doubled Find x and the direction of the current in the third wire
