🔍 Key Concepts

• Components of a standard magnetic compass binnacle • Difference between correcting permanent magnetism vs. induced magnetism • Which parts of the ship’s structure create horizontal soft iron effects

💭 Think About

• Ask yourself: which of these devices is specifically associated with correcting errors caused by horizontal soft iron near the compass? • Consider which options are mainly for correcting permanent magnetism instead of induced magnetism. • Think about where each item (magnets, bar, spheres) is placed and what kind of magnetic field direction it is meant to counteract.

✅ Before You Answer

• Identify which choice is classically used to correct quadrantal deviation caused by soft iron. • Separate devices that correct fore-and-aft or athwartship permanent magnetism from those that correct soft iron effects. • Verify which item is normally seen as a vertical bar beside or in the binnacle, and which as spheres on either side.
