Question
A 20cm long solenoid has 4300 turns of wire. Inside this solenoid is a second one, also 20cmlong but with 2000 turns of wire. Part A If a 2.7A current flows in each solenoid in the same direction, what is the magnitude of magnetic field inside the inner solenoid? Express your answer to two significant figures and include the appropriate units.Part B What A 20cm long solenoid has 4300 turns of wire.
