A student is performing a physics lab to test Faraday's Law. She places an 85-turn wire loop of radius 5 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 1.1 V. Calculate the initial strength of the magnetic field. (Give your answer in tesla but don't include the units.)
