PROBLEM 2 - 10 points A square loop travels at a constant velocity of 10 cm/s to the right through a region of magnetic field. The magnetic field is confined to the outlined rectangular region outlined. The magnetic field is directed into the page in the left half of this region, and out of the page in the right half. The small squares on the diagram measure 10 cm x 10 cm, and the loop is shown at time t=0....

In a region with a constant magnetic field as shown, there are
two conducting frictionless horizontal rails, a resistor and some
conducting wire along the left side and a conducting bar on the
right side that is free to slide left or right. The bar is
initially at rest but at time zero a force is applied to the bar
pulling it to the right so that the distance s increases with
time.

Learning Goal: To understand the terms in Faraday's law and to be able to identify the magnitude and direction of induced emf. Faraday's law states that induced emf is directly proportional to the time rate of change of magnetic flux. Mathematically, it can be written as E=???B?t, where E is the emf induced in a closed loop, and ??B?t is the rate of change of the magnetic flux through a surface bounded by the loop. For uniform magnetic fields the...
