Introduction
We will learn about the application of Ampere's law in toroid.
Pre-Requisites:
About Ampere's Law and magnetic field.
Activity:
Calculate the field inside a toroid using Ampere's law and comment on the nature of the field.
Real Life Question:
Why in a toroid field calculation is easy?
Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| Toroid | A hollow circular frame of wire wound closely insulated from each other. |
Learning aids / Gadgets
| Gadgets | How it can be used |
|---|---|
| Text book | Find the expression of magnetic field in a solenoid in your text book. |
Real life uses :
In Transformers, Transducers etc.
Places to visit :
Your school lab, text book
Practical examples around us
| Examples | Explainations |
|---|---|
| Electromagnets | Toroids can be used as electromagnets as they have the capacity to control magnetic field. |
What you learn in Theory:
A toroid is a hollow circular frame of wires wound closely. Field outside the toroid & inside the open space of toroid is zero and field inside the toroid is uniform.
What you learn in Practice:
If solenoid is bent in the form of circular frame it becomes toroid. Magnetic field due to both the systems are same as well.
