Chapter Name: Playing With Magnets
Activity Name: Make your own magnetic compass in Playing With Magnets
The experiment involves creating a homemade magnetic compass using a magnetized needle and a cork. By floating the cork in a glass of water and observing the direction in which the needle points, we can determine the North-South direction.
- Magnetized needle
- Light cork
- Glass of water
- Detergent (to help the cork float freely)
Step by Step Procedure:
- Take a magnetized needle.
- Tape the needle securely to a light cork.
- Fill a glass with water.
- Add a small amount of detergent to the water to help the cork float freely.
- Gently place the cork with the attached needle onto the surface of the water.
- Allow the cork to float and stabilize.
- Observe the direction in which the magnetized needle points.
- Note that the needle aligns itself in a particular direction.
- Be careful while handling the magnetized needle to avoid any accidental injuries.
- Ensure that the needle is securely taped to the cork to prevent it from falling off.
- Use a light cork to ensure proper buoyancy.
Lesson Learnt from Experiment:
By creating a homemade magnetic compass, we can observe that the magnetized needle aligns itself in the North-South direction.
This experiment demonstrates the basic principle of how a magnetic compass works, where the needle aligns with Earth’s magnetic field, with one end pointing towards the North Pole and the other towards the South Pole.
