Question

Магнитный поток пронизывающий замкнутый проводящий контур, равномерно убывает в течение 0,2 с до нуля. Возникающая в контуре ЭДС индукции составляет 0,6 В. Определите максимальное значение магнитного потока. С подробным решением пожалуйста

Answer 1

Δt = 0,2 с
Ф₂ = 0
Ei = 0,6 В
Ф₁ - ?
Запишем закон электромагнитной индукции
Ei = - ΔФ / Δt = - (Ф₂ - Ф₁) / Δt => Ф₂ - Ф₁ = - Ei *Δt => Ф₁ = Ф₂ + Ei*Δt
Ф₁ = 0 + 0,6 В * 0,2 с = 0,12 Вб

Answer 2

Calculation of the Maximum Magnetic Flux

To determine the maximum value of the magnetic flux, we need to use Faraday's law of electromagnetic induction, which states that the induced electromotive force (EMF) in a closed conducting loop is equal to the rate of change of magnetic flux through the loop.

The formula for Faraday's law is:

EMF = -dΦ/dt

Where: - EMF is the induced electromotive force - Φ is the magnetic flux - dt is the change in time

In this case, we are given that the induced EMF in the circuit is 0.6 V and the change in time is 0.2 s.

Using the formula, we can rearrange it to solve for the change in magnetic flux:

dΦ = -EMF * dt

Substituting the given values:

dΦ = -0.6 V * 0.2 s

dΦ = -0.12 Vs

Since the magnetic flux is decreasing uniformly, the change in magnetic flux is negative.

To find the maximum value of the magnetic flux, we need to determine the initial
