Physics
EMI and AC for JEE Main & Advanced — flux, phases, and circuits that repeat yearly
How Faraday's law and phasors show up in JEE circuit problems, and what to standardise early for each exam.
On JEE Main
Main tests Lenz's law direction, self and mutual inductance, and AC circuit quantities (impedance, resonance, power factor) in single-correct MCQ format. Transformer and eddy current applications appear as short conceptual questions.
On JEE Advanced
Advanced uses multi-correct and integer formats with moving conductors in non-uniform fields, LC oscillation energy exchanges, and complex impedance phasor diagrams. Integer-type questions on induced EMF require setting up and integrating flux correctly.
How to practise
Use PracticeJEE's EMI and AC topic when you want mixed conceptual + numeric sets after DC circuits revision.
