A rectangular conducting frame of the dimension shown is dragged at constant speed $\backslash ($ v$\_\{$o$\}\backslash )$ from a region of no magnetic field through two regions of different uniform magnetic field oriented as shown below.

Choose your answers for parts $($a$)$ and $($b$)$ from the graphs to the right.

Part $($a$)$

Which graph $($A$,$ B $,$ C$,$ D$,$ E$,$ or F$)$ best represents the magnetic flux through the loop as a function of time? Take flux coming out of the page as positive.

Part $($b$)$

Which graph $($A$,$ B $,$ C $,$ D$,$ E $,$ or F$)$ best represents the current induced in the conducting frame as a function of time. Take a counterclockwise current as positive.

Part $($c$)$

What is the magnitude of the induced EMF as the frame is entering the $\backslash ($ B$\_\{$o$\}\backslash )$ region?

Part $($d$)$

What is the magnitude of the induced EMF as the frame is entering the $\backslash ($ B$\_\{$o$\}/3\backslash )$ region?
