) A long straight wire on the z-axis carries a current of 10.0 A in the +z direction. A circular loop in the xy-plan has a radius 0.10 m and is centered at x = 0.25 m on the x-axis. What current must the loop support for the magnitude of the magnetic field at the center of the loop to be zero. A) 0.79 A B) 1.13 A C) 0.42 A E) zero 1.27 A ) A long straight wire on the z-axis carries a current of 10.0 A in the +z direction.
