Figure 4.
The eight panels are labelled a to h. Panel a shows 12 conductors arranged in a circle of radius 0.03 metres. Panel b shows 10 conductors aligned along the y-axis. Panel c shows 100 conductors in a 10-by-10 hexagonal grid. Panel d shows conductors filling a trapezoidal slot without overlap. Panels e and f show 12 conductors placed along a sinusoidal curve between 0 and 0.2 metres. Panel g shows 5 conductors at the vertices of a square. Panel h shows 15 conductors forming the shape of the letter A.Real parts of the current density J distributions corresponding to the models generated based on user prompts (a)–(d)
