Answer: current I is 144amp(A)
Explanation: The force per lenght F/L, current l, and separation distance r are related by the formula
F/L = permeability of space* I²/2*pi*r
Permeability of free space is 1.257*EXP {-6} Henry/meter
F/L is 0.244 N/m, pi is 3.142,
r is 1.7cm which is equal to 0.017meter.
I is what we are looking for.
Now we have after substitution,
0.244
= 1.257*EXP {-6} * I²/(2*3.142*0.017)
After cross multiplying and making I² subject of formula we have,
0.0261/(1.257*EXP {-6}) = I²
I = √{20736.7} =144ampere(A)
That means in each of the jumper wire there is 144amp(A)
