This diagram covers Magnetic Field Patterns within Magnetic Fields for GCSE Physics. Revise Magnetic Fields in Magnetism for GCSE Physics with 14 exam-style questions and 12 flashcards. Use this page as part of a wider topic revision path rather than treating it as an isolated fact. It is section 3 of 13 in this topic. Focus on the labels, the relationships between parts, and the explanation that turns the diagram into an exam-ready answer.
📊 Magnetic Field Patterns
Figure: Magnetic field lines around a bar magnet — always N to S outside the magnet, densest at the poles.
RULES for drawing field lines:
- Field lines go from NORTH to SOUTH (outside magnet)
- Arrows show direction a north pole would move
- Closer lines = STRONGER field
- Lines never cross
- Field strongest at the poles
Practice questions for Magnetic Fields
