Two long and parallel straight wires A and B carrying currents of 8.0 A and 5.0 A in the same direction are separated by a distance of 4.0 cm. Estimate the force on a 10 cm section of wire A.

Current in wire A, $I_{1} = 8 A$
Current in wire B, $I_{2} = 5 A$
Force exerted on 10cm section of wire A,
$B = \frac{μ_{o} 2 I_{1} I_{2} l}{4 π r} = 2 \times 10^{- 5} T$
Attractive force normal to A towards B, because current direction same.
