Magnetic field- B-x3BC-oI2-x3C0-rB-1-2-xD7-10-x2212-5TCurrent flows from east to west- point is below the powerline-Using right hand thumb rule- direction of B is southward-

A horizontal overhead power line carries a current of 90 A in east to west direction. What is the magnitude and direction of the magnetic field due to the current 1.5 m below the line?

Magnetic field, $B = \frac{μ_{o} I}{2 π r}$
$B = 1.2 \times 10^{- 5} T$
Current flows from east to west, point is below the powerline.
Using right hand thumb rule, direction of B is southward.
