🔍 Key Concepts

• Flinders bar and what type of magnetism it corrects for in a magnetic compass • Quadrantal spheres and what type of deviation they are intended to correct • Manufacturer or regulatory guidance on inspection / adjustment intervals for magnetic compass correctors

💭 Think About

• Ask yourself whether these correctors can themselves become magnetized over time, and what that would mean for compass accuracy. • Consider how often a ship’s magnetic compass is normally checked or adjusted, and whether these correctors would reasonably follow a similar schedule. • Think about which option sounds like a practical maintenance interval for something that directly affects safe navigation.

✅ Before You Answer

• Verify whether Flinders bar and quadrantal spheres can acquire permanent magnetism and thus need periodic checks. • Check typical shipboard compass maintenance or deviation check schedules from your study materials. • Eliminate any choices that conflict with normal safety‑critical equipment inspection practices (too rarely or never checked).
