Two circular loops of wire lie in the x-y plane, centered at the origin. The radius of the loops is 5.00 and 7.00 cm. The current in the outer loop is 50.0 mA in the clockwise direction. a. If the current in the inner wire is also 50.0 mA in the clockwise direction, what is the magnetic field strength at the origin? b. What current magnitude and direction in the inner wire will cause the magnetic field to be zero at the origin?
