When do I use EMF = −dΦ/dt in Magnetism & Electromagnetic Induction, and what does it mean?
Faraday's law of electromagnetic induction.
EMF = −dΦ/dt — Faraday's law of electromagnetic induction. Use it when: flux is changing with time. Always check the condition holds before plugging in numbers.
Key point
EMF = −dΦ/dt
