Homework Statement
One possible concern with MRI (magnetic resonance imaging) is turning the magnetic field on or off too quickly. Bodily fluids are conductors, and a changing magnetic field could cause electric currents to flow through the patient. Suppose a typical patient has a maximum cross-section area of 6.8×10−2 m^2.
What is the smallest time interval in which a 5.5 T magnetic field can be turned on or off if the induced emf around the patient's body must be kept to less than 9.0×10−2 V?
