What is the direction of the magnetic field inside a current-carrying solenoid? (2019)
Step 1: Understand what a solenoid is. A solenoid is a coil of wire that creates a magnetic field when an electric current passes through it.
Step 2: Identify the direction of the electric current in the solenoid. The current flows through the wire in a specific direction.
Step 3: Use the right-hand rule to determine the direction of the magnetic field. Point your thumb in the direction of the current flow, and your fingers will curl in the direction of the magnetic field lines.
Step 4: Recognize that the magnetic field inside the solenoid is uniform and directed from the north pole to the south pole of the solenoid.
Step 5: Conclude that the magnetic field inside a current-carrying solenoid points from the north end to the south end.
