Consider a conducting ring of radius a and resistance R. Case I We first place the ring in a constant magnetic field B = shown in Figure 9. Bo pointing into the page as a) Calculate the magnetic flux through the ring. Express the answer in terms of the defined parameters in the problem.
In some facilities, real-time MRI is used to monitor a treatment. This imaging allows the treatment to be adjusted to achieve optimum results. However, the devices that deliver the treatment can themselves produce magnetic fields that interfere with the imaging. In one case, a device produces a 65 T static field parallel to the 1.5 T field in the MRI machine Part A By how much does this additional field change the proton's procession frequency?

A closed current path is made from two different circular arcs as shown in the figure below. The larger arc has radius 3.0 cm and covers one quarter of the circle, and the smaller arc has radius 1.0 cm and covers the remaining three quarters of the circle. If the current is 1.5 A going counterclockwise, what is the magnitude of the B-field at the center of the circular arcs? Express your answer to the nearest µT.
