a rectangular loop of wire with length $2\mathrm{.}2$ cm$,$ width and resistance b $=0\mathrm{.}8$ cm$,$ R $=0\mathrm{.}4$ m$2$ is placed near an infinitely long wire carrying cur$-$ rent i $=4\mathrm{.}7$A The loop is then moved away from the wire at constant speed v $=3\mathrm{.}2$mm $/$ s When the center of the loop is at distance r $=1\mathrm{.}5$b what are $($a$)$ the magnitude of the magnetic flux through the loop and $($b$)$ the current induced in the loo
