Question

Магнитный поток, пронизывающий замкнутый контур, возрастает с 10–2 до 6 ∙ 10–2 Вб за промежуток времени 0,001 с. Определить среднее значение э. д. с. индукции, возникающей в контуре.

Answer 1

E=Ф2-Ф1/t=6*10^-2-10^-2/0,001=50 В

Answer 2

Calculation of Average Value of Induced Electromotive Force

To determine the average value of the induced electromotive force (emf) in the circuit, we need to calculate the change in magnetic flux and the time interval over which this change occurs.

Given: - Initial magnetic flux, Φ1 = 10^(-2) Wb - Final magnetic flux, Φ2 = 6 * 10^(-2) Wb - Time interval, Δt = 0.001 s

The change in magnetic flux (ΔΦ) can be calculated as the difference between the final and initial magnetic flux:

ΔΦ = Φ2 - Φ1

Substituting the given values:

ΔΦ = (6 * 10^(-2)) - (10^(-2)) = 5 * 10^(-2) Wb

The average value of the induced electromotive force (emf) can be calculated using Faraday's law of electromagnetic induction:

Average emf = ΔΦ / Δt

Substituting the values:

Average emf = (5 * 10^(-2)) / (0.001) = 50 V

Therefore, the average value of the induced electromotive force (emf) in the circuit is 50 V.

Please note that the above calculation is based on the given information and the application of relevant principles.
