What is the magnetic field inside a long solenoid when the current is flowing through it? (2023)

Step 1: Understand what a solenoid is. A solenoid is a long coil of wire that creates a magnetic field when an electric current flows through it.
Step 2: Know that when current flows through the solenoid, it generates a magnetic field inside it.
Step 3: Recognize that the magnetic field inside a long solenoid is uniform, meaning it has the same strength and direction at every point inside.
Step 4: Remember that the magnetic field lines inside the solenoid are parallel to each other and aligned with the axis of the solenoid.
