Determine (a) the magnetic energy density in the field. (b) he enrgy stored in the magnetic field with in the solenoid.

For (a) i use the formula Ub= (B^2)/(2Uo) and i get 8.1x10^6

Is this correct?

For (b) I am not quite sure what to do. I know i must use the length and diameter to find B. or maybe not

I need some guidance.

Thank You
