Q: In a solenoid carrying current, what is the direction of the magnetic field inside the solenoid?
Solution: The magnetic field inside a solenoid is uniform and directed along the axis of the solenoid.
Steps: 5
Step 1: Understand what a solenoid is. A solenoid is a coil of wire that is wound in a spiral shape.
Step 2: Know that when electric current flows through the wire, it creates a magnetic field.
Step 3: Remember the right-hand rule: if you curl the fingers of your right hand in the direction of the current flow in the coils, your thumb points in the direction of the magnetic field inside the solenoid.
Step 4: Realize that the magnetic field inside the solenoid is uniform, meaning it has the same strength and direction at all points inside.
Step 5: Conclude that the magnetic field inside the solenoid is directed along the axis of the solenoid.
