An air-filled toroidal solenoid has 390 turns of wire, a mean radius of 15.0 cm , and a cross-sectional area of 5.00 cm2 .
Part A
If the current is 5.40 A , calculate the magnetic field in the solenoid.
B=__T
Part B
Calculate the self-inductance of the solenoid.
L=__H
Part C
Calculate the energy stored in the magnetic field.
U=__J
Part D
Calculate the energy density in the magnetic field.
u=__J/m^(3)
Part E
Find the answer for part D by dividing your answer to part C by the volume of the solenoid.
u=__J/m^(3)
