(a) The current ratio between a central Z-shaped wire and two U-shaped control wires allows us to precisely tune the trap geometry. For a symmetric current flow, the trap minimum is positioned below the center of the Z-wire, with the long trap axis aligned to the horizontal direction. (b) 2d cut through the trapping potentials for

at a constant external Bias field of 
, respectively. (d,e) Cuts through the radial trap minimum of the same potentials to show the axial trap deformation.
