Introduction
We can apply Ampere's law to the system where some symmetry is there in order to simplify the calculation of magnetic field.
Pre-Requisites:
Knowledge about Biot-Savart law and magnetic field.
Activity:
Find out in which physical systems we can apply Ampere's law? And also calculate the field in those systems.
Real Life Question:
How we find the inductance of any solenoid?
Key Words / FlashCards

|---|---|
| Solenoids | Ampere's law is used to calculate the field in the solenoids. |
What you learn in Theory:
Using the Ampere's law we can calculate the field in the systems where we find symmetry. For that we have to choose Amperian loop and apply Ampere's law.
What you learn in Practice:
When there is a system with a symmetry, Ampere’s law enables an easy evaluation of the magnetic field, much the same way Gauss’ law helps in determination of the electric field.
