Given:
The number of turns in the solenoid, N=8
The induced voltage, V=4.00 V
The time interval, Δt=6.00 s
To find:
The average change in the magnetic flux.
Explanation:
The emf induced due to the changing magnetic flux is given by the equation,
[tex]V=N\frac{\Delta\phi}{\Delta t}[/tex]Where Δφ is the change in the magnetic flux.
On rearranging the above equation,
[tex]\Delta\phi=\frac{V\times\Delta t}{N}[/tex]On substituting the known values in the above equation,
[tex]\begin{gathered} \Delta\phi=\frac{4.00\times6.00}{8} \\ =3.00\text{ Wb} \end{gathered}[/tex]Final answer:
Thus the average change in the magnetic flux through one turn in the solenoid is 3.00 Wb. Thus the correct answer is option B.
