Introduction
We will learn about the magnetic field produced by a current carrying element.
Pre-Requisites:
Knowledge about magnetic field.
Activity:
Compare the magnetic field produced with the electrostatic field.
Real Life Question:
Is the expression of magnetic field for vacuum valid for air as well?

Practical examples around us
| Examples | Explainations |
|---|---|
| Every current carrying element | Every current carrying wire around us produces magnetic field. |
What you learn in Theory:
The magnetic field produced by a current carrying element is inversely proportional to the distance with point at which field is to be calculated and the element.
What you learn in Practice:
Biot-Savart law for the magnetic field is analogous to coulomb's law in electrostatic field.
