Answer 1

DФ=L*dI=600*(30-5)*10^-3=15 Вб

Answer 2

Calculation of the Change in Magnetic Flux in a Solenoid

To calculate the change in magnetic flux in a solenoid with an inductance of 600 H, resulting from a change in current from 5 mA to 30 mA, we can use the formula:

ΔΦ = L * ΔI

Where: - ΔΦ is the change in magnetic flux - L is the inductance of the solenoid - ΔI is the change in current

Substituting the given values into the formula, we have:

ΔΦ = 600 H * (30 mA - 5 mA)

Calculating the change in current:

ΔI = 30 mA - 5 mA = 25 mA

Substituting the value of ΔI into the formula:

ΔΦ = 600 H * 25 mA

To calculate the change in magnetic flux, we need to convert the current from milliamperes (mA) to amperes (A):

25 mA = 0.025 A

Substituting the value of ΔI into the formula:

ΔΦ = 600 H * 0.025 A

Calculating the change in magnetic flux:

ΔΦ = 15 A * H

Therefore, the change in magnetic flux in the solenoid, resulting from the change in current from 5 mA to 30 mA, is 15 A * H.

Please note that the calculation assumes a linear relationship between the change in current and the change in magnetic flux, which may not always be the case in practical scenarios.
