An overhead electric power line carries a maximum current of 165 A. What is the magnitude of the magnetic field at a point 2.40 m directly below the power line?
Soo...
I = 165A
L = 2.40m
Equations i have learned areee
(1) F = ILBsin(theta)
(2) F = |q|vBsin(theta)
(3) r = mv / |q|B
(4) B = (constant)I/R
im unsure
. i tried equation 4 . but that didnt work. any help would be awesome!
