Prob. 4 A 1.2m-long metal bar is pulled to the right at a steady rate of 2.5m/s perpendicular to a uniform, 1.50T magnetic field. The bar rides on a pair of conducting, parallel rails connected through a resistance R = 7.50 so the apparatus forms a complete electrical circuit. Ignore the resistance of the bar and the rails and all gravitational effects. [b]What is the magnitude of the induced current (in units of A)?
