The magnetic field inside a solenoid is uniform at all points if the solenoid is infinite in length and the current density is uniform. This conclusion is based on Ampère's Law, which states that the magnetic field is directly proportional to the current flowing through the solenoid. For practical applications, finite solenoids may exhibit non-uniformity at the ends, but the uniformity holds true in the ideal case of an infinite solenoid.
