A student is performing a physics lab to test Faraday's Law. She places an 85-turn wire loop of radius 7 cm perpendicular to a magnetic field. She takes 0.9 seconds to decrease the magnetic field to a final value of 2.3 T, and measures an induced voltage (in the loop) of magnitude 0.45 V. Calculate the initial strength of the magnetic field. (Give your answer in tesla)
