Solve the following question:
Question: A solenoid used to produce magnetic fields for research purposes is 2.5m long, with an inner radius of 26cm and 1400 turns of wire. When running, the solenoid produced a field of 1.3T in the center.
Part A: Given this, how large a current does it carry?
I have tried this so many times and I cannot get the right answer! Any help with steps will be great! Thank you!
