🔍 Key Concepts

• Compass deviation vs. variation • Purpose of vertical magnets vs. horizontal magnets in a standard magnetic compass binnacle • How heel and trim (inclination) affect a ship’s magnetic field and compass

💭 Think About

• Think about what type of compass error appears when the vessel heels or trims, changing its inclination from the vertical. Which option mentions that effect most directly? • Vertical magnets are placed under or above the compass card. Ask yourself: are they mainly counteracting a vertical or horizontal disturbing magnetic field? And is that field permanent or induced? • Compare the roles: vertical soft iron spheres and horizontal fore‑and‑aft/athwartship magnets. Which errors do each typically correct?

✅ Before You Answer

• Identify which choice refers to an error that changes as the ship’s inclination (heel/trim) changes, not just heading alone • Distinguish between induced magnetism in soft iron and permanent magnetism of the ship’s structure • Confirm from your compass theory notes what a single vertical magnet specifically corrects, and match that phrase carefully to one of the options
