(a) Orientation of a zigzag wire, magnetization M (open arrows), and external H//, HZ fields. (b) – (f) Variation of magnetic potential energy within “point charge” model with distance d from the HH vertex along the wire. Orientations of H// and Hz are indicated. Inset photographs show close correlation between locations of a microsphere with a diameter of 2.8 μm on the wire and the calculated local energy minimum position.
