At a certain location there is a constant horizontal magnetic field pointing to the east. A square loop of wire is placed in this field. At time A the bottom of the loop is resting on the floor (which is insulating), and the plane of the square loop is vertical and perpendicular to the magnetic field. The loop tips over and at time B it is flat on the floor. For this situation...

A) Before the loop starts to tip over, the induced current is flowing southward through the bottom side of the square

B) While the loop is tipping over, the induced current is flowing northward through the bottom side of the square

C) Current is induced to flow in the loop because the area is changing

D) The magnetic flux is greatest after the loop has tipped over

E) The induced current is flows in one direction only

A loop of wire sits in a uniform magnetic field, everywhere pointing toward you. Due to a changing magnetic flux through the loop, an induced current flows in the wire, clockwise as shown. The area of the loop is J. 1.63 m2 , and the magnetic field initially has magnitude K. 0.61 T. (a) Suppose that, over a time period of L. 1.47 s, the magnetic field changes from its initial value, producing an average induced voltage of M. 8.7...
