Two parallel rods having length \(12 \mathrm{~cm}\) and a separation of \(50 \mathrm{~cm}\) carry current from left to right. If current through wire 1 is \(10 \mathrm{~A}\) and through wire 2 is \(12 \mathrm{~A}\), calculate the magnitude and direction of the magnetic force per unit length exerted by wire 1 on wire 2 .
