🔍 Key Concepts

• Compass deviation and what causes it • Difference between permanent magnetism of the ship and induced magnetism in soft iron • Purpose of the different correctors on a binnacle: vertical magnets, horizontal magnets, and soft iron spheres

💭 Think About

• Think about where the soft iron spheres are placed in relation to the compass and whether they can move up/down or in/out, and what kind of magnetic effect that would best correct. • Recall which kind of magnetism depends on the ship’s heading in the Earth’s magnetic field, and which is more or less fixed in the ship’s structure. • Match each answer choice to a specific correcting device on the binnacle (e.g., which one is handled by vertical magnets? which by fore‑and‑aft or athwartship magnets? which by the spheres?).

✅ Before You Answer

• Be clear on the difference between permanent magnetism of the ship and induced magnetism in soft iron. • Identify which type of deviation varies most with changes in magnetic latitude and heading. • Confirm which binnacle corrector (spheres vs. vertical/fore‑and‑aft magnets) is associated with the horizontal soft iron near the compass.
