During transcranial magnetic stimulation (TMS) treatment, a magnetic field typically of magnitude 0.40 T is produced in thebrain using external coils. During the treatment, the current in the coils (and hence the magnetic field in the brain) rises fromzero to its peak in about 90 us. Assume that the magnetic field is uniform over a circular area of diameter 2.0 cm inside thebrain. What is the magnitude of the average induced emf | around this area in the brain during the treatment?|E| =1.833IncorrectV
