Magnetic Flux
चुंबकीय फ्लक्स
In this Class 12 Physics topic from Electromagnetic Induction, students learn how magnetic flux measures the magnetic field passing through a surface. They explore the relation Φ = B·A = BA cos θ, understand how area, field strength, and surface orientation affect flux, and identify its SI unit, the weber. The topic also connects changing magnetic flux with induced emf through Faraday’s law, helping explain electromagnetic induction in practical systems.
