A magnetic field points perpendicularly into the page. As shown, single square loop, moving at a constant velocity, starts outside the region with the magnetic field, moves across, and then leaves the region. The graph below the diagram represents the induced emf. As seen from above, a counterclockwise emf is regarded as positive. In which direction did the loop move over the plane of the page? Why is this the case?
As shown below, a wire loop is immersed in a constant uniform B-field (all across the screen & beyond) that is pointing down. The loop's area is

- The problem below explores the basic principles behind electric generators, which we will discuss in class in detail. A 505 turn circular loop coil with a diameter of 3.9cm is initially held perpendicular to the Earth's magnetic field. The coil is then rotated in 7.6ms by 90 degrees, so the plane of the coil is parallel to the magnetic field. The average emf induced in the coil is 7.2V. Find the value of the Earth's magnetic field (in T) inducing the current in the coil.As an approximation, assume that the magnetic flux in the coil changes at a constant rate between its maximum and minimum values. Note that (see the previous problem) the flux through the coil is 505 times larger than if it was made out of one wire loop.arrow_forwardThe loop in the figure below is rotated out of the plane of the drawing while B is kept constant. You can assume the rotation axis is along the horizontal direction in the figure. a) Does the magnitude of the flux through the loop increase or decrease with time? (Assume the loop has not had time to rotate by more than 90°.) Increase/Decrease? b) If the loop has only rotated a small amount, will the induced current be clockwise or counterclockwise?arrow_forwardA rectangular loop of sides I and w moves at speed v with respect to a long straight wire with current I as shown in the diagram below.
