Abstract: Abstract Arising from: D. B. Strukov, G. S. Snider, D. R. Stewart & R. S. Williams Nature 453, 80–83 (2008)10.1038/nature06932 In 1971, Chua suggested1 that there should in principle exist a circuit element linking electrical charge, q, and magnetic flux, ϕ. Strukov et al.2 claim recently to have found such a link. However, here I point out that Chua’s suggestion was in fact preceded by experimental evidence3,4,5 for magneto-electric effects whereby magnetic and electrical signals are interconverted. When the stimulus is magnetic and the response is electrical, the linear magneto-electric coupling constant5, α, is typically reported as dP/dH, where P represents the electrical polarization and H represents the applied magnetic field. The coupling constant could equally be presented as dq/dϕ if divided by the permeability of free space.
