A cоil is wrаpped with 300 turns оf wire оn the perimeter of а circulаr frame (radius = 8.0 cm). Each turn has the same area, equal to that of the frame. A uniform magnetic field is turned on perpendicular to the plane of the coil. This field changes at a constant rate from 20 to 80 mT in a time of 20 ms. What is the magnitude of the induced emf in the coil at the instant the magnetic field has a magnitude of 50 mT? Report your answer in volts(Hint 1: Determine the explicit form for the magnetic field as a function of time)(Hint 2: Solve for time when the field strength is 50 mT)
