Suppose an overhead cable is carrying an electric current of 190A due west (east-to-west) in a region where earth's magnetic field is 50pT pointing north. What is the magnitude of the magnetic force acting on a 75 m segment of this cable? (Is this force a cause for concern?. for comparison, a small bird weighs about 1 N or so.)
