A horizontal rod with a length of 0.250 is mounted on a balance and carries a current. At the location of the rod a uniform horizontal magnetic field has a magnitude of 6.70×10−2 and direction perpendicular to the rod. The magnetic force on the rod is measured by the balance and is found to be 0.190 . What is the current?
