Question 1 of 27070

Which term is given to magnetism which is present only when the material is under the influence of an external field?

🔍 Key Concepts

• Types of magnetism in nautical compasses (permanent, induced, and sub-permanent) • How external magnetic fields (like Earth’s field) affect soft iron vs hard steel • The meaning of magnetism that disappears when the external field is removed

💭 Think About

• Ask yourself: Which type of magnetism exists ONLY because an outside magnetic field is acting on the material, and vanishes when that field is gone? • Consider: Which options describe magnetism that is always present in the material, even without any outside influence? Eliminate those. • Think about how soft iron inside a ship behaves: when it’s taken out of the Earth’s magnetic field, does it keep its magnetism or lose it?

✅ Before You Answer

• Identify which term refers to magnetism that depends entirely on an external field and does not remain afterward. • Eliminate any term that means magnetism that stays in the material after the field is removed (that would be permanent or leftover magnetism). • Check that the term you choose is the one commonly used for magnetism caused by Earth’s magnetic field acting on soft iron in a vessel.
