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?
