What should be the rate of change of the magnetic flux delta F / delta t (Wb / s) in order for the induction EMF modulus in the circuit to be equal to 10 V?
EMF = 10 V.
ΔФ / Δt -?
According to Faraday’s law of electromagnetic induction, the electromotive force of the EMF induction is directly proportional to the rate of change of the magnetic flux ΔF / Δt: EMF = – ΔF / Δt.
The “-” sign shows the direction of the induction current in the conductor, Lenz’s rule.
ΔF / Δt = 10 Wb / 1 s.
The rate of change of the magnetic flux ΔФ / Δt = 10 Wb / 1 s means that during the time Δt = 1 s, the magnetic flux changes by ΔФ = 10 Wb.
Answer: the rate of change of the magnetic flux is ΔF / Δt = 10 Wb / 1 s.
