Subject: 1133795165.Ph Re:Lorentz force on a Helmholtz coil exerted from a conduct

I received an answer from Prater Brian D., but I don't think it is complete. I
asked for the total force that is exerted on the Helmholtz coil from the
conductor .I don't know how you calculated the magnetic field around the
conductor but from Ampere law we know that B=mp.I/2πR for a straight conductor,
where R is distance from the conductor and for the Helmholtz arrangement it
varies from R/2 to R.5^0.5/2. Can you please give me a precise answer for the
Force? You may assume that Helmholtz coils have only one turn (N=1) and that
current is the same in both the coil and the conductor. Thank you in advance!
