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?

Key Words / FlashCards
Key Words Definitions (pref. in our own words)
Biot-Savart law A law to calculate the magnetic field due to any element.
Learning aids / Gadgets
Gadgets How it can be used
Text book Read the text book to find the expression of magnetic field due to current carrying element.
Real life uses :

Used to detect current, to measure magnetic field,

Places to visit :

Your school physics lab, Refer to text book

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.
