Please forward this question to Mr.John Free. Arrangement Description: Two
dc-current coils are side-by-side (Helmholtz) in a distance R and a straight
dc-current carrying conductor is put right between them (perpendicular to the
coilĘs axis) at a distance R/2 from each coil. Assume that the conductorĘs
length is R, and the amperage in the coils and conductor is the same I. What is
the force that is exerted on the conductor (because of Helmholtz coils magnetic
field) and on the coils (because of conductorĘs magnetic field) ? I guess you
will say that action-reaction says they are equal, but can you help me calculate
them for verification?
