🔍 Key Concepts

• Magnetic flux density (B) vs. magnetic field strength (H) in basic electromagnetism • Definition of permeability in magnetic materials • How reluctance and residual magnetism are described (they relate to magnetism, but in different ways)

💭 Think About

• Ask yourself: which term is defined specifically as a proportionality between B and H in a material? • Which of the options represents a ratio or constant that links how strongly a material responds to an applied magnetic field? • Which options describe properties like leftover magnetism or opposition to magnetic flux, rather than a direct ratio of B to H?

✅ Before You Answer

• Write the relationship between B and H as a simple formula and identify the constant in between. • Check which option is defined in textbooks as a measure of how easily a material can be magnetized by a magnetic field. • Eliminate any option that does not explicitly involve a ratio or proportionality between flux density and field strength.
