Parts a,b

There is a solenoid with no markings. It has a length of 15.5 cm and diameter of 3.2 cm. You want to find the number of turns there are. So you find a power supply that you ramp up at the current at the rate of 18 Ms. You put a single loop of wire around the solenoid, as illustrated, with a galvanometer that can measure the induced EMF. The loop has a diameter of 4.8 cm. You measure an induced EMF of 20 uV. \\Blue cylinder shows region with magnetic eld B. A) How many turns of wire is there in the Solenoid? B) Calculate the magnitude of the electric eld in the wire loop
