cenario$-1$: The cross sign means an $8$A current going into the page, the other current $10A$ is out of the page, displayed by a dot. Each curve is a circular path. $C_1$ has radius $1cm,C_2$:$2\mathrm{.}25cm,$ and $C_3$:$4cm.$

Scenario$-2$: A square $12-$turn coil has an edge$-$length equal to $40\mathrm{.}0cm$ and carries a current of $3A.$ It produces a uniform magnetic field vec$(B)=0\mathrm{.}250$That$(i)+0\mathrm{.}500$That$(k).$

Scenario$-1$

NOTE: Questions $($a$),($b$)$ follow Scenario #$1,$ and $($c$),($d$)$ follow Scenario #$2.$

$($a$)$ Find $o{\displaystyle \underset{\phantom{}}{\overset{\phantom{}}{}}}$vec$(B)*dvec(l)$ for each path, assuming that each integral is to be evaluated in the counterclockwise direction.

$($b$)$ Which path, if any, can be used to find the combined magnetic field of the currents? Find the field intensity.

$($c$)$ Find $($i$)$ the magnetic moment of the coil, $($ii$)$ the torque exerted on the coil, and $($iii$)$ the potential energy of the coil.

$($d$)$ If You bring an identical loop along the $z-$axis near the present one with no battery connected. At what times do you get an $i_{\text{i}\text{n}\text{d}}$ reading in the incoming loop? Find directions for your explanations. Note that the current loop in the prompt is not changing.
