Question
![A copper rod of length 0.94 m is lying on a frictionless table (see the drawing). Each end of
the rod is attached to a fixed wire by an unstretched spring that has a spring constant of k
=93 N/m. A magnetic field with a strength of 0.32 T is oriented perpendicular to the surface
of the table. (a) What must be the direction of the current in the copper rod that causes the
springs to stretch? (b) If the current is 10 A, by how much does each spring stretch?
