Which describes the magnetic field inside a long solenoid carrying a current?
Strong and uniform, with parallel field lines that are evenly spaced
Weak and uniform, with parallel field lines that are evenly spaced
Strong and non-uniform, with field lines closest together at the ends
Zero everywhere, because all the field lines are outside the solenoid
