9. Two concentric circular wire loops of radij r = 12 cm and r2 24 cm are located m an
xy plane, as shown below. The smaller loop carries a CW current I = 6 A and the
bigger loop carries a CCW current I2 = 9 A.
a) Find the magnitude and direction of the magnetic field created by the current li at
the center of the loop.
b) Find the magnitude and direction of the magnetic field created by the current I2 at the center of the
loop.
c) Find the magnitude and direction of the net magnetic field at the center of the loops.
d) The direction of the current in the inner/smaller loop is reversed. Find the magnitude and direction of
the net magnetic field at the center of the loop in this case.
