Understanding
- I can describe a magnetic field as a vector field that acts on moving charges, currents and magnetic materials, and give its unit. (Guide: “What a magnetic field is”)
- I can explain why there are no magnetic monopoles and predict the poles of the pieces of a cut magnet. (Guide: “Dipoles, poles and field lines”; Practice Q1)
- I can explain that magnetic dipoles come from moving electrons, and that permanent and induced magnetism are both alignment of dipoles. (Guide: “Where magnetism comes from”)
- I can compare ferromagnetic, paramagnetic and diamagnetic materials and give an example of each. (Guide: “How different materials respond”; Practice Q4)
- I can describe permeability, state that μ₀ is a constant, and explain why a material’s μ is not. (Guide: “Magnetic permeability”; Practice Q2)
Representations and skills
- I can draw the field lines of a bar magnet as closed loops, with arrows outside and inside the magnet. (Guide: Figure 1)
- I can predict which way a compass points at any point near a magnet. (Practice Q3)
- I can add two perpendicular magnetic fields to find the direction a compass points. (Guide: Worked example 1; Practice Q5)
- I can sketch Earth’s dipole field and label its magnetic poles correctly. (Guide: “Earth as a magnet”; Practice Q6)
Reasoning
- I can use μ/μ₀ data to classify a material and justify the classification. (Guide: Worked example 2)
- I can justify the direction of a field inside a magnet or inside Earth using the closed-loop rule. (Practice Q6c)
- I can use data to show how a dipole’s field decreases with distance and test a claimed relationship. (Practice Q7)
