Sub Topic Name : Magnetic Field Due To A Current Element, Biot-Savart Law |
We will learn about the magnetic field produced by a current carrying element.
Knowledge about magnetic field.
Compare the magnetic field produced with the electrostatic field.
Is the expression of magnetic field for vacuum valid for air as well?
Key Words | Definitions (pref. in our own words) |
---|---|
Biot-Savart law | A law to calculate the magnetic field due to any element. |
Gadgets | How it can be used |
---|---|
Text book | Read the text book to find the expression of magnetic field due to current carrying element. |
Used to detect current, to measure magnetic field,
Your school physics lab, Refer to text book
Examples | Explainations |
---|---|
Every current carrying element | Every current carrying wire around us produces magnetic field. |
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.
Biot-Savart law for the magnetic field is analogous to coulomb's law in electrostatic field.
