🔍 Key Concepts

• Static magnetic fields vs. electric fields – which materials affect magnetism rather than just insulate electricity? • Magnetic permeability – ability of a material to concentrate magnetic field lines. • Difference between magnetic materials (ferromagnetic) and good electrical insulators.

💭 Think About

• Ask yourself: which option is known to be attracted by a magnet or used in everyday magnets or transformers? • Which of these substances can ‘guide’ or ‘concentrate’ magnetic field lines rather than block electricity? • Which listed materials are primarily used as electrical insulators, and which one is commonly associated with magnetism?

✅ Before You Answer

• Identify which substance is ferromagnetic (strongly affected by magnetic fields). • Eliminate substances that are mainly electrical insulators with little or no magnetic effect (think plastics, glass, ceramics). • Recall that effective shielding from static magnetic fields usually uses materials with high magnetic permeability.
