A physician is using a device, with a thin circular coil of current-carrying wire of radius 1.7 mm, to stimulate neurons in a patient's brain. The coil is placed directly against the patient's skull, and everywhere within the area of the coil, the magnetic field changes from zero to 1.50 T (perpendicular to the plane of the coil) in 100 ms.   What is the magnitude of the average emf induced around the circumference of this circular area in the brain? Express your answer in units of mV.
