Problem

Two mutually perpendicular infinitely long conductors coincide with the

x

-axis and

y

-axis, carrying steady currents

I_1 = 8\,\text{A}

(along positive

x

) and

I_2 = 6\,\text{A}

(along positive

y

) respectively. Determine the magnitude of the resultant magnetic field at the point

(0,\,0,\,3\,\text{cm})

on the positive

z

-axis. a)
