How much will the magnetic flux, penetrating the circuit, change in a time of 0.5 s, if an EMF of induction equal to 2 V appears in the circuit?
Initial data: Δt (time interval during which the magnetic flux changed) = 0.5 s; ε (EMF of induction that arose with the circuit) = 2 V.
The magnitude of the change in the magnetic flux is determined from the formula for calculating the EMF of induction: ε = | ΔФ / Δt |, whence ΔФ = ε * Δt.
Let’s make a calculation: ΔF = ε * Δt = 2 * 0.5 = 1 Wb.
Answer: The magnetic flux will change by 1 Wb.
