Question: A circular loop of wire carrying current produces a magnetic field. What is the shape of the magnetic field lines inside the loop? (2020)

Options:

  1. Straight lines
  2. Concentric circles
  3. Parallel lines
  4. Uniform field

Correct Answer: Uniform field

Exam Year: 2020

Solution: 

Inside the loop, the magnetic field lines are nearly uniform and parallel, indicating a strong and consistent magnetic field.

Questions & Step-by-Step Solutions

A circular loop of wire carrying current produces a magnetic field. What is the shape of the magnetic field lines inside the loop? (2020)
  • Step 1: Understand that a circular loop of wire carries an electric current.
  • Step 2: Recognize that when current flows through the wire, it creates a magnetic field around the loop.
  • Step 3: Focus on the area inside the loop where the magnetic field is present.
  • Step 4: Visualize the magnetic field lines inside the loop; they are straight and run parallel to each other.
  • Step 5: Conclude that these parallel lines indicate that the magnetic field inside the loop is strong and consistent.
  • Magnetic Field of a Current-Carrying Loop – The magnetic field inside a circular loop of wire carrying current is uniform and parallel, indicating a strong magnetic field.
