0^4 A) / (2π.133) .. .. ►B = 15.......
A lightning bolt may carry a current of 1.00 * 10^4 A for a short period of time. What is the resulting magnetic field 133 m from the bolt? Assume that the bolt extends far above and below the point of observation.

______ µT

-
Assume the bolt acts as a long straight wire
B = μₒ.i/(2πr)

B = (4π^-7)(1.0^4 A) / (2π.133) .. .. ►B = 15.0μT
