Prob. 4 A 1.2m-long metal bar is pulled to the right at a steady rate of 2.5m/s perpendicular to auniform, 1.50T magnetic field. The bar rides on a pair of conducting, parallel rails connectedthrough a resistance R = 7.5N so the apparatus forms a complete electrical circuit. Ignore theresistance of the bar and the rails and all gravitational effects.[b]What is the magnitude of the induced current (in units of A)?

As the rod moves with uniform velocity, the magnetic flux through the loop formed by the rod and the…
