In the figure, a rectangular loop of wire with length $a=2\mathrm{.}4cm,$ width $b=0\mathrm{.}64cm,$ and resistance $R=0\mathrm{.}44m$ is placed near an infinitely long wire carrying current $i=7\mathrm{.}3A.$ The loop is then moved away from the wire at a constant speed $v=2\mathrm{.}4m\frac{m}{s}.$ When the center of the loop is at distance $r=1\mathrm{.}4cm,$ what are $($a$)$ the magnitude of the magnetic flux through the loop and $($b$)$ the current in amperes induced in the loop?
