The resistance of the electrical circuit is 20 ohms. What amount of electricity will pass along the circuit when the magnetic flux permeating the circuit changes by 6 · 10-8 Wb?

According to the law of electromagnetic induction, when the magnetic flux changes with time, an EMF arises in the circuit, equal to εi = Δ Ф / Δ t.
The current strength in the circuit is determined from Ohm’s law I = εi / R in this formula, we replace the EMF of induction by the ratio of the change in flux to time I = (Δ Ф / Δ t) / R. The amount of electricity that will pass along the contour is denoted by Δ q, and is calculated according to the formula.
Δ q = I * Δt = (Δ Ф / Δt) * Δt / R = Δ Ф / R, we substitute the data into the formula and calculate.
Δ q = 6 * 10 ^ -5 Wb / 20 Ohm = 3 * 10 ^ -5 C
