Magnetic Flux Density & the Vector Potential
Inside this lesson
- Define the magnetic vector potential A and explain why B must be a curl, not a gradient
- Connect Gauss's law for magnetism (∇·B = 0) to the existence of A
- Use Stokes' theorem to express magnetic flux as the circulation of A
- Compute single-turn flux and total flux linkage for a multi-turn coil
