A magnetic field B $=65\mathrm{.}0$ mT points in the $+$y$-$direction. A rectangular loop of wire with an area of $200$ cm$2,$ which is initially in the xz$-$plane, rotates into the xy$-$plane $($that is$,$ through $90$ degrees$)$ as shown. This process is smooth and takes $1\mathrm{.}2$ seconds.

Part A

What is the magnetic flux through the loop at t$=0\mathrm{.}9$s $?$

Express your answer with the appropriate

units.

also,

B$)$

What is the magnitude of the induced emf at t$=$t$=0\mathrm{.}9$ s$?$

C$)$

What is the maximum induced emf?
