A solenoid 30.0 cm long and with a cross-sectional area of 0.600 cm^2 contains 460 turns of wire and carries a current of 70.0 A.
A. Calculate the magnetic field in the solenoid. B=0.135 T
B. Calculate the energy density in the magnetic field if the solenoid is filled with air.
C. Calculate the total energy contained in the coil's magnetic field (assume the field is uniform).
D. Calculate the inductance of the solenoid.
