Calculate the force per unit length on a long straight wire carrying current `4A` due to parallel wire carrying current `6A` current. Distance between the wires `=3cm`.

Text Solution

Verified by Experts

Here, `I_1=4A`, `I_2=6A`,
`r=3cm=3xx10^-2m`
Force per unit length, `F=(mu_0)/(4pi)xx(2I_1I_2)/(r)`
`=10^-7xx(2xx4xx6)/(3xx10^-2)=1*6xx10^-4Nm^-1`
