🔍 Key Concepts

• Components of a standard magnetic compass correction system (what each corrector is used for) • Difference between soft iron correctors and permanent magnets in compass adjustment • Which items are themselves magnets versus pieces of soft iron influenced by the ship’s field

💭 Think About

• For each choice, identify which items are actual magnets and which are soft iron or other instruments. • Ask yourself: which correctors could themselves become permanently magnetized and therefore must be checked before use? • Eliminate any items that are not part of the standard compass correcting system or are primarily indicators rather than correctors.

✅ Before You Answer

• Verify which parts of the system are permanent magnets used to correct for certain components of deviation. • Confirm that Flinders bar and quadrantal spheres are made of soft iron and depend on the ship’s magnetic field, not on their own permanent magnetism. • Check whether dip needle is a correcting device or a separate instrument used for measuring magnetic dip.
