Q

Where is induced magnetism found?

🔍 Key Concepts

• Induced magnetism vs. permanent (retentive) magnetism in a ship’s structure • Difference between hard iron and soft iron in compass deviation theory • How easily different types of iron become magnetized by the Earth’s magnetic field

💭 Think About

• Ask yourself: which type of iron is easily magnetized when placed in a magnetic field, and loses that magnetism quickly when the field is removed? • Which type of iron is associated with permanent magnetism that stays even when the external field changes or is removed? • In compass correction, which type of material (hard or soft iron) is used to represent magnetism that changes with the ship’s heading and Earth’s field?

✅ Before You Answer

• Be clear on the definition of induced magnetism: magnetism caused by an external field and typically temporary • Distinguish hard iron (retains magnetism, permanent) from soft iron (readily magnetized and demagnetized) • Verify which option matches the material that is easily and temporarily magnetized by the Earth’s magnetic field around the ship
