Shown in the following figure is a long, straight wire and a single-turn rectangular loop, both of which lie in the plane of the page. The wire is parallel to the long sides of the loop and is 0.50 m away from the closer side. At an instant when the emf induced in the loop is 2.0 V, what is the time rate of change of the current in the wire?
In the figure below, the conducting loop has fallen a short distance and is now falling at a constant velocity, vterminal. The loop has sides of length s=0.50 m, mass 30.0 g, and resistance R=1.00 Ω. If B=7.50 T and is directed into the page, answer the following question:
What is the magnitude of the force pulling down on this loop and according to Lenz’s Law, in which direction will an induced current in the loop travel? Make sure to show how you know and all your work.
As shown is a graph of the induced emf versus time for a coil of N turns rotating with angular speed ω in a uniform magnetic field directed perpendicular to the coil’s axis of rotation. What If? Copy this sketch (on a larger scale) and on the same set of axes show the graph of emf versus t (a) if the number of turns in the coil is doubled, (b) if instead the angular speed is doubled, and (c) if the angular speed is doubled while the number of turns in the coil is halved.
