12. How does a compass work?(1 point)
Answers
GPT 3.5
A compass works by utilizing Earth's magnetic field to determine direction. The needle of the compass is magnetized and aligned with the Earth's magnetic field, which points toward the magnetic North Pole. By using this reference point, the compass can accurately show which direction is north, south, east, and west.
13. How could you make a compass? (2 points)
GPT 3.5
To make a simple compass, you will need the following materials:
- A sewing needle or a small metal pin
- A small piece of cork or foam
- A small dish of water
- A magnet
Here's how you can make a compass:
1. Magnetize the needle or metal pin by rubbing it against a magnet in one direction multiple times.
2. Carefully push the needle through the piece of cork or foam so that it floats on the water surface.
3. Place the cork with the needle on the surface of the water in a small dish or container.
4. Allow the needle to settle and align itself with Earth's magnetic field, pointing north and south.
5. Use this homemade compass to determine direction by observing which way the needle points.
This simple homemade compass demonstrates the basic principles of how a compass works by using a magnetized needle floating on water to align with the Earth's magnetic field.
