A conducting rod is free to slide on horizontal, frictionless rails separated by 2.0 m. At a particular time, the rod is sliding at 4.0 m/s to the right, as shown. A uniform magnetic field is directed into the page. If a current of 40 mA is generated in the circuit at this time, and the resistance R is 0.36 Ω, what is the magnitude of the magnetic field between the rails?
