🔍 Key Concepts

• Earth’s magnetic field components: horizontal vs. vertical (dip) component • How the magnetic dip angle (inclination) changes from magnetic equator to magnetic poles • What part of the field a magnetic compass card actually responds to

💭 Think About

• Think about where the compass needle would tend to point most straight down or up, and what that means for the horizontal part of the field at that location • Consider where on Earth the magnetic field lines are parallel to the Earth’s surface versus where they are steeply inclined • Ask yourself: Does a magnetic compass work best near the poles, the equator, or somewhere in between? Why?

✅ Before You Answer

• Be clear on the difference between total magnetic force and its horizontal component • Recall how magnetic dip (inclination) is approximately 0°, 90°, or intermediate values at different regions of the Earth • Before choosing, picture how longitudinal (north-south) field lines intersect the Earth’s surface at the equator vs. the poles and how that affects the horizontal component available to drive the compass magnets
