Homework Statement
Two long straight wires in the xy plane are
parallel to the x axis. One wire is at y =
−8 cm and the other wire is at y = 8 cm. The
current in each wire is 24 A and the currents
are in the negative x direction.
The permeability of free space is 4 π ×
10−7 T · m/A.
Find the magnitude of the force per unit
length exerted by one wire on the other. An-
swer in units of μN/m.
Homework Equations
F/L= Uo*ia*ib/(2*pi*d)
The Attempt at a Solution
what i did is that i assumed that one of the wires is at point zero , so i used the equation aboove plugging in these values
F/L= (4*pi*10^-7*24*24)/(2*pi*.08) = i got 1440
which is wrong !
is there what I am doing wrong or is it just a calculation mistake
need your help !
