What is the magnetic field inside a long solenoid when the current is steady? (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 passes through it.
Step 2: Know that when the current is steady, it means the current is constant and not changing over time.
Step 3: Recognize that the magnetic field produced by the solenoid is inside the coil and is directed along the length of the solenoid.
Step 4: Remember that the magnetic field inside a long solenoid is uniform, meaning it has the same strength and direction at every point inside the solenoid.
Step 5: Conclude that the magnetic field inside a long solenoid is parallel to the axis of the solenoid when the current is steady.
