A solenoid 22.0 cm longand with a cross-sectional area of 0.500cm2 contains 415turns of wire and carries a current of 85.0 A.
a) Calculate the magnetic field in the solenoid.
b) Calculate the energy density in the magnetic field if thesolenoid is filled with air.
c) Calculate the total energy contained in the coil's magneticfield (assume the field is uniform).
d) Calculate the inductance of the solenoid.
