(25pts) A 0.200 m long metal bar is pulled to the left by an applied force F, and the bar moves at a constant speed of 8.0 m/s. The bar rides on parallel metal rails connected through a R=3.0 A resistor as shown. (Ignore the resistance of the two parallel rails and the bar.) The circuit is in a region of uniform magnetic field of strength B=0.80 T, and the field is directed out of the page. a. At what rate is the magnetic flux I changing in the loop? b. What is the induced current in the loop? What force must be applied to the metal bar to keep it moving at the constant speed? c.
