Answer:
a) The magnitude of the current is 24.19 A
b) The angle is 90°
Explanation:
a) Given:
B = magnetic field = 44 µT = 44x10⁻⁶T
r = distance = 11 cm = 0.11 m
The current is:
[tex]B=\frac{\mu I}{2\pi r} \\I=\frac{2B\pi r}{\mu } =\frac{2*44x10^{-6}*\pi *0.11}{4\pi x10^{-7} } =24.19A[/tex]
b) Because the current flows from the west to the east, therefore, the angle is 90 degrees from the north.
