A. Use Ampere's Law to find the general equation for the magnetic field in an infinitely long solenoid.
b. Find the magnetic field inside the solenoid.
By Ampere's Law:
close integral [B*dl] = muo*total current:
let number of turns/length = n
hence, for length ...
With good explanations and calculations, the problems are solved. The magnetic fields inside a solenoid are given. The Ampere's Law functions are given.
