Introduction
We will learn about the magnetic field produced by a current carrying circular loop.
Pre-Requisites:
Knowledge about magnetic field.
Activity:
Compare the magnetic field at the center of the loop with the magnetic field at some distance from the loop.
Real Life Question:
Is the expression of magnetic field for vacuum valid for air as well?

What you learn in Theory:
The magnetic field produced by a current carrying loop at the center is inversely proportional to the radius of the loop.
What you learn in Practice:
Right Hand Thumb Rule can be used to to find the direction of the magnetic field. According to which,"Curl the palm of your right hand around the circular wire with the fingers pointing in the direction of the current. The right-hand thumb gives the direction of the magnetic field."
