An infinitesimal current element located at the origin (x, y, z) = (0, 0, 0) carries current I in the positive y direction. At which of the following locations is the magnetic field due to this current element the smallest?

1) x=L, y=0, z=02) x=0, y=L, z=03) x=0, y=L, z=L4) x=0, y=0, z=L5) x=L, y=0, z=L6) x=L, y=L, z=0
