Q: What is the magnetic field inside a long solenoid carrying current?
Solution: The magnetic field inside a long solenoid is uniform and parallel to the axis of the solenoid.
Steps: 4
Step 1: Understand what a solenoid is. A solenoid is a long coil of wire that can create a magnetic field when an electric current passes through it.
Step 2: Know that when current flows through the solenoid, it generates a magnetic field inside and around it.
Step 3: Recognize that the magnetic field inside a long solenoid is not just random; it is uniform, meaning it has the same strength and direction at every point inside the solenoid.
Step 4: Identify that the direction of the magnetic field inside the solenoid is parallel to the axis of the solenoid, which means it runs along the length of the solenoid.
