Introduction
only moving charges produce the magnetic field. Light is electromagnetic in nature.
Pre-Requisites:
Basic introduction about electrostatic charges, and moving charges.
Activity:
Spread some iron fillings near the current carrying wire and see the pattern that how fillings are spread out.
Real Life Question:
"Why magnetic needle is deflected when kept near the current carrying wire?"
Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| Electromagnetic | Combination of electric and magnetic effects. |
Learning aids / Gadgets
| Gadgets | How it can be used |
|---|---|
| Galvanometer | It shows the deflection when kept near the magnetic field environment. |
Real life uses :
Light around us, is electromagnetic in nature. This property of light helps us to understand its characteristics. Also presence of electric as well as magnetic field can be determined by this property.
Places to visit :
School physics lab to see the basic galvanometer and circuits
Practical examples around us
| Examples | Explainations |
|---|---|
| Light | Light is electromagnetic in nature. |
| Cars, Scooter, Speakers | All these use electromagnetism. |
What you learn in Theory:
Moving charges always produce magnetic field. Light is electromagnetic in nature.
What you learn in Practice:
when there is flow of current in any wire, there is always electric as well as magnetic field established. The combination of both is electromagnetism.
