I need proficient help in the following problem:
Problem: A solenoid is producing a magnetic field of B = 7.5 x 10-3 T. It has N = 1900 turns uniformly over a length of a = 0.35 m.
Part I: Express the current I in terms of B, N and d.
Part II: Calculate the numerical value of I in amps.
Please use as much detail as possible in solution!!!
