Understanding electromagnetism. II. Problems with radiation

For pt.I see ibid., vol.2, no.6, p.273-80 (1993). Alternative ideas about what is meant by the `electromagnetic field´ are explored further, following on from the previous article. It is suggested that a change in view may help to reduce the difficulties which many engineers have in understanding the operating principles of simple electromagnetic devices. Of particular interest here are the conditions under which a circuit radiates. A change in approach makes the use of displacement currents and Poynting vectors unnecessary
