🔍 Key Concepts

• Permanent magnetism vs. induced magnetism in a steel hull • Which correctors are permanent magnets and which are soft iron • What type of magnetism causes heeling error (when the ship rolls or heels)

💭 Think About

• For each option, ask: does this corrector mainly deal with magnetism that is always present, that changes with heading, or that changes with heel? • Which corrector is specifically placed to counteract the vertical component of the ship’s magnetism? • Among the listed correctors, which one is designed to handle a combination of effects rather than just one type (permanent only or induced only)?

✅ Before You Answer

• Identify which correctors (from the choices) are permanent magnets and which are soft iron devices • Recall that soft iron correctors mainly handle induced magnetism that changes with the Earth’s field and heading • Recall which corrector is adjusted while watching the compass as the vessel is heeled side to side, indicating it is handling both permanent and induced vertical effects
