Answer:
B = 1.67 μ T
Explanation:
given,
current, I = 1 x 10⁴ A
r = 120 m
treating lightning bolt as long straight conductor
[tex]B=\dfrac{\mu_0I}{2\pi r}[/tex]
[tex]B=\dfrac{4\pi \times 10^{-7}\times 1 \times 10^4}{2\pi\times 120}[/tex]
resulting magnitude would be equal to
B = 16.67 x 10⁻⁶ T
B = 1.67 μ T
The resulting magnetic field is equal to B = 1.67 μ T
Answer:
1.67 x 10^-5 Tesla
Explanation:
Current, i = 1 x 10^4 A
distance, d = 120 m
The formula for the magnetic field due to long straight current carrying conductor is given by
[tex]B =\frac{\mu _{0}}{4\pi }\times \frac{2i}{r}[/tex]
[tex]B =10^{-7}\times \frac{2\times 10^{4}}{120}[/tex]
B = 1.67 x 10^-5 Tesla
