What is the magnitude | &| of the emf induced in the coil during the time interval? 18 = V TOOLS x10During a transcranial magnetic stimulation (TMS) treatment, a magnetic field, typically of magnitude 5.00 T, is produced in the brain using external coils. During the treatment, the current in the coils (and hence the magnetic field in the brain) rises from zero to its peak in about 85.0 us . Assume that the magnetic field is uniform over a circular area of diameter 2.00 x 10-2 m inside the brain. What is the magnitude of the average induced emf around this region of the brain during the treatment? average induced emf: Vp A Illturn circular coil of radius 2.2? cm and negligible resistance is immersed in a uniform magnetic eld that is ; perpendicular to the plane of the coil.
