Fields
A-Level Physics Fields Tutor — Gravity, Electric & Magnetic
Fields is the conceptual pinnacle of A-Level Physics, unifying gravitational, electric, and magnetic phenomena under a single framework. This topic consistently separates top grades from average ones. Our tutors use a systematic approach to help you master the equations, graphs, and essay-style questions that examiners set.
Board: Cambridge A-Level / AQA / OCR / Edexcel
Topics Covered
- Newton's law of gravitation
- Gravitational field strength and potential
- Orbital motion and escape velocity
- Coulomb's law and electric field strength
- Electric potential and equipotentials
- Uniform and radial fields
- Magnetic flux and flux density
- Electromagnetic induction
Exam Tips
- Tip 1:Field lines go from high to low potential; equipotentials are perpendicular
- Tip 2:Orbital period: T² ∝ r³ (Kepler's third law)
- Tip 3:Potential energy at infinity = 0; gravitational PE is always negative
- Tip 4:Know the shapes of field graphs: 1/r² vs 1/r for field strength vs potential
