Q

Which would influence a magnetic compass?

🔍 Key Concepts

• Magnetic compass deviation and what causes it • Difference between magnetic fields created by metal objects vs. electrical equipment • How different shipboard systems can create local magnetic interference

💭 Think About

• Think about which items on the list can create or disturb a magnetic field near the compass. • Consider why we keep magnetic compasses away from certain materials and installations on a vessel. • Ask yourself: on a real ship, what things would the compass adjuster be most concerned about when locating and swinging the compass?

✅ Before You Answer

• Identify which options can create or alter a magnetic field near the compass. • Recall that both ferrous metals (like iron or steel) and electric currents can affect compass readings. • Before choosing, ask: if this item were close to the compass, would it be a concern during a compass adjustment?
