SUMMARY
The calculation of magnetic force on a cylinder in a gradient field involves understanding the interaction between two current-carrying rings. The scenario described includes an annulus with outer radius ro and inner radius ri, creating a magnetic field gradient due to the gap width of ri - r. This gradient affects the magnetic force experienced by the centered cylinder. Utilizing principles from electromagnetism, specifically the force between current-carrying conductors, provides a method to derive the magnetic force in this configuration.
