A segment of wire carries a current of 20 A
along the x axis from x = −6 m to x = 0 and
then along the z axis from z = 0 to z = 7.2 m.
In this region of space, the magnetic field is
equal to 51 mT in the positive z direction.
What is the magnitude of the force on this
segment of wire?
The Attempt at a Solution
Fb = ( 20 A ) (7.2m ) ( .051m )
the question asked for " the magnitude of the force on THIS SEGMENT of wire" so i thought to just plug in 7.2m but it turned out to be wrong so i added the 6m as well but it was wrong again. help =[
