A current of 10A is established in a long wire along the positive z-axis. Find the magnetic field `(vec B) at the point (1m , 0 , 0).

Equal currents are flowing in three infinitely long wires along positive x,y and z -directions. The magnetic field at a point (0,0-a) would be ( i= current in each wire)

Same current i is flowing in the three infinitely long wires along positive x-,y- and z-directions. The magnetic filed at a point (0,0,-a) would be

Same current i is flowing in the three infinitely long wires along positive x-,y- and z-directions. The magnetic filed at a point (0,0,-a) would be
