For a research project, a student needs a solenoid thatproduces an interior magnetic field of 0.0300 T. She decidesto use a current of 1.00 A and a wire 0.500 mm in diameter. She winds the solenoid in layers on an insulating form 1.00 cm indiameter and 10.0 cm long. Determine the number of layers of wire needed and the total length of the wire.
