Final answer:
The equation emf = -N(Φ/t) represents Faraday's law of electromagnetic induction.
Step-by-step explanation:
The equation emf = -N(Φ/t) represents Faraday's law of electromagnetic induction. It relates the electromagnetic force (emf) induced in a circuit to the rate of change of magnetic flux through the circuit.
The negative sign indicates that the induced emf opposes the change in magnetic flux.
