Big superconducting magnets are employed in hospitals to form pictures of the interior of the body by magnetic resonance imaging (MRI). For this reason the patient is shoved in the coils of the magnet, where the magnetic field is around 1.5 T. Assume that the patient is shoved into the magnetic field in a time of 10 s. Approximate the emf induced about the patient's trunk, 0.90 m in circumference. Must the patient be shoved into the magnetic field more gradually?
