Three long, parallel conductors each carry a current of $\backslash ($ I$=1\mathrm{.}84\backslash$mathrm$\{$~A$\}\backslash ).$ The figure below is an end view of the conductors, with each current coming out of the page. Taking $\backslash ($ a$=1\mathrm{.}60\backslash$mathrm$\{$~cm$\}\backslash ),$ determine the magnitude and direction of the magnetic field at the following points.

$($a$)$ point $\backslash ($ A $\backslash )$

magnitude $\backslash (\backslash$mu $\backslash$mathrm$\{$T$\}\backslash )$

direction $---$Select$---$

$($b$)$ point $\backslash ($ B $\backslash )$

magnitude $\backslash (\backslash$mu $\backslash$mathrm$\{$T$\}\backslash )$

direction $---$Select$---$

$($c$)$ point $\backslash ($ C $\backslash )$

magnitude $\backslash (\backslash$mu $\backslash$mathrm$\{$T$\}\backslash )$
