Answer:
[tex]B = 0.00782N / (Am) = 7.82 * 10^{-3} T[/tex]
Explanation:
Under the definition of force on a magnetic field we proceed to make the point a,
A) [tex]F = ILBsin (\theta)[/tex]
Since the field is perpendicular, then \theta = 0
[tex]F = ILB[/tex]
[tex]B = \frac {F} {IL} = \frac {1} {I} \frac {f} {L}[/tex]
[tex]B = 0.00782N / (Am) = 7.82 * 10^{-3} T[/tex]
b) The direction of the magnetic field would be done in + Zdirection. This when understanding that the vector extends along the z + axis of the formula [tex]\vec {F} = i (\vec {l} x \vec {B})[/tex]
