Compass

The video explains how a compass works by pointing north due to Earth's magnetic field. It describes the compass's components: a magnetic needle, a pivot, and a marked disk. The Earth acts like a magnet with magnetic poles, attracting the compass needle. This alignment helps users determine all directions.

What are the three main components of a compass?

• A magnet, a string, and a base

• A needle, a spring, and a dial

• A pointer, a wheel, and a plate

• A needle, a pivot, and a disk

How does the Earth behave in relation to a compass?

• As a giant magnet

• As a gravitational force

• As a large electric field

• As a static object

Where is the Earth's magnetic field strongest?

• At the Earth's core

• In the middle of the ocean

• At the magnetic poles

• At the equator

Why does a compass needle point north?

• Because it is affected by wind direction

• Because it is heavier on one side

• Because it aligns with the Earth's magnetic poles

• Because it is attracted to the sun

What additional information can a compass provide besides north?

• All other cardinal directions

• The time of day

• The weather conditions

• The altitude
