1] Two long straight parallel conductors each carrying a current of 24 amps flowing in the same direction are fixed at a distance of 40mm from each other. A third parallel conductor is placed equidistant from the other two and carries a current of 30 amps.(adsbygoogle = window.adsbygoogle || []).push({});

Show that the force on the third conductor is a maximum when its distance from the other conductors is 28.2mm and calculate the force per metre at this distance.

----

I know that F=BIL, is this sufficient for solving this problem? just need a little guidence.
