Suppose we put a $7-$turn rectangular coil $($with sides of length d $=8\mathrm{.}1$ cm and w $=1\mathrm{.}7$ cm$)$ in a changing magnetic field. The magnetic field is given by B $=$ B$0+$ B$1*$t$2$ pointing at angle of $=35$ through the coil. At t $=4\mathrm{.}5$ s$,$ what is the magnitude of the induced voltage in the coil? Take B$0=0\mathrm{.}049$ T and B$1=0\mathrm{.}29$ T$.$

$.$

$($a$)$ As the square loop is spinning, the magnetic flux through the loop is constantly changing, which we could represent with the following magnetic flux versus time graph. Which of the following points on the graph could represent the instant shown in the picture above? Choose all that could be true.

Select all that are True.

A

B

C

D

E

F

G

H

$$Tries $0/4$

$($b$)$ Given the magnetic flux versus time graph from Part $($a$),$ which of the following graphs would be the corresponding induced voltage versus time graph for the loop?

None of these

$($c$)$ At the moment shown above in the figure, the loop is lying flat on the page and is rotating along the dotted axis. The right side of the loop is about to come out of the page, the left side into the page. At this particular instant in time, what direction is the induced current?

Clockwise

Counterclockwise

No induced current at this instant
