long horizontal wire carries a current of
48 A. A second wire, made of 1.00-mm-
diameter copper wire and parallel to the
first, is kept in suspension magnetically
5.0 cm below. (a) Is the lower wire in
stable equilibrium? (b) Determine the
magnitude and direction of the current in
the lower wire. rho (density of Cu wire) is
8900 kg/m^3 and g=9.8 m/s^2*
