What is the magnetic field inside a hollow conductor carrying current?

What is the magnetic field inside a hollow conductor carrying current?

Correct Answer: Zero

Step 1: Understand what a hollow conductor is. A hollow conductor is a tube-like object that can carry electric current.
Step 2: Know that when electric current flows through a conductor, it creates a magnetic field around it.
Step 3: Recognize that the magnetic field is strongest near the surface of the conductor and gets weaker as you move away from it.
Step 4: Learn about Ampere's law, which helps us understand the relationship between electric current and magnetic fields.
Step 5: Apply Ampere's law to a hollow conductor. Inside the hollow part (the empty space), there is no current flowing.
Step 6: Conclude that since there is no current inside the hollow conductor, the magnetic field inside it is zero.
