Compute each part of following problem given below:
Problem: You would like to store 8.9J of energy in the magnetic field of a solenoid. The solenoid has 550 circular turns of diameter 8.2cm distributed uniformly along its 26cm length.
Part A: How much current is needed?
Part B: What is the magnitude of the magnetic field inside the solenoid?
Part C: What is the energy density (energy/volume) inside the solenoid?
I need help to determine the magnitude of the magnetic field inside the solenoid and express your answer using two significant figures.
