A uniform magnetic field that we control points out of the page, as shown in the diagram, and changes with time as shown in the graph. A single wire loop, 0.15 m in radius and with 9.0 . resistance, is placed flat on the page, as shown, so that the magnetic field points out, perpendicular to the plane of the loop. There is no battery in the loop! a) Graph the induced current in the loop as a function of time. Use positive values to indicate clockwise current and negative to indicate counterclockwise current. Include the correct scales on your graph b) What is the field contributed by the current in the center of the loop during the first 2 seconds? Compare this to the external field during most of this time interval, and comment on the impact on the net field during most of the interval. (In other words, Lenz's law says the induced field tries to undo the change in field; is the induced current going to be successful at doing so?) в ст) 0.5 t(s) 2
