Q

What is the term used for the horizontal angle between the magnetic meridian and the north-south line axis line of the magnetic compass?

🔍 Key Concepts

• Magnetic meridian vs. compass needle axis – what each one represents • Difference between variation, deviation, and compass error • How individual compass errors combine to form total error

💭 Think About

• First, ask yourself: which quantity is measured specifically between magnetic north and the ship’s magnetic compass north line? • Think about which term describes local magnetic influences on the vessel and which describes the Earth’s magnetic field vs. true north. • Which of these choices is a single specific angle, and which is a combination of more than one angle?

✅ Before You Answer

• Identify which term is defined as the angle between magnetic north and compass north. • Verify which option refers to the effect of magnetic material on the vessel (this is a different angle). • Confirm which term is the sum of two separate angles rather than a direct angle between two meridians.
