🔍 Key Concepts

• Consider what permanent magnetism in the ship actually depends on (steel structure, previous magnetizing forces) • Think about how the horizontal component of the Earth's magnetic field changes as you move from higher latitudes toward the magnetic equator • Recall how deviation is produced by the interaction between the ship’s magnetism and the Earth’s magnetic field

💭 Think About

• Ask yourself: if the Earth’s magnetic field becomes more horizontal and weaker in the vertical component near the magnetic equator, how does that affect the compass error caused by the ship’s own permanent magnetism? • Would a change in latitude (toward the magnetic equator) tend to make the ship’s permanent magnetic effect on the compass stronger, weaker, or unchanged? Why? • Think about whether the ship’s permanent magnetism itself changes much, or whether it’s the effect on the compass that is changing as the background field changes

✅ Before You Answer

• Be clear on the difference between permanent magnetism of the ship and induced magnetism from the Earth’s field • Focus on what happens to the resulting deviation, not just the ship’s internal magnetism, as latitude changes • Verify how the Earth’s magnetic field strength and direction vary between higher latitudes and the magnetic equator before choosing your option
