Simulation: Motional emf Rail Analyzer

Slide a conducting rod through a uniform field and inspect how area, flux, induced emf, current, and polarity update together.

Appears in: 20.1 Motional emf and Magnetic Flux, 20.2 Faraday's Law and Flux Linkage, 20.3 Lenz's Law and Direction Workflows, 20.4 Self-Induction and RL Transients, 20.5 AC Generators and Alternating Current, 20.6 RMS Power and Transformer Links

v-+Loop area A = Lx changes as the rod slides, so flux changes at a constant rate.
