Question


In the figure below, the rectangular loop is being pulled to the right at a constant speed v. A constant current I flows in the long wire in the direction shown.

(a) Calculate the flux through the loop, in terms of the parameters shown and any constants.

(b) Using Faraday's Law, calculate the magnitude of the emf induced in the loop

(c) Check your answer in part (b) by calculating the motional emf in each segement of the loop.

(d) Using Lenz's Law, *carefully explain the direction of current induced in the loop.

(e) Check your answer in part (d) by *carefully explaining the direction of the magnetic force on the moving charges in the loop.


Please be sure to show all of the steps in your calculations :)
