1. The problem statement, all variables and given/known data 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. 2. Relevant equations F/L= Uo*ia*ib/(2*pi*d) 3. 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 im doing wrong or is it just a calculation mistake need your help !!
