61.7N, pointing west

Explanation:

Magnetic for is a vector quantity:
#vecF=IveclxxvecB#

#F=ILBsintheta#

#F=6180A*130m*82.2xx10^-6T*sin(69) =61.7AmT=61.7N#

Apply the right hand rule by curling the finger of the right hand from north downward to ground, i.e., from #vecl# to #vecB#. In doing so, the thumb is pointing to the west.

Thus, the 61.7 force pushes the power line westward.
