  1. [No. 9] Can a magnetic circuit work without air ?

    Recently the U.K. Magnetics Society sent a list of 10 questions for their magazine MagNews, in which the first question was “What is your favourite magnetic material?” In a hurry…

  2. [No. 8] Hysteresis

    At the JMAG Users’ Conference in Strasbourg last October, Hiroyuki Sano (JSOL) and Yves Thiolière (Powersys) gave a detailed class tutorial on the hysteron, a defined trapezoidal …

  3. [No. 7] Peripheral, marginal, second-order, inexact . . . and IMPORTANT!

    The finite-element method is very rarely exactly correct. Now surely that is an outrageous thing to say on the JMAG website! But what do we mean by exactly? The finite-element met…

  4. [No. 6] The Periodic Table of Electric Machines

    When the archaeologists dig us up in 5,000 years’ time, they will find a large number of electric motors and generators. Who knows if they will understand what they find? They w…

  5. [No. 5] Formulas and Equations

    What’s the difference between a formula and an equation? Take the examples,

  7. [No. 3] Görges diagram

    The polygonal diagram of H. Görges (Das Görgessche Durchflutungspolygon) dates from 1907. Although it is highly developed in German literature, until recently it has been rare in …

  8. [No. 2] ABC of engineering calculations today

    Most engineering calculations take the path of analysis or simulation, shown in Fig. 1, A. Analysis has been established for a long time; but simulation is more recent, especially…

  9. [No. 1] When is a fluxmeter not a fluxmeter?

    A fluxmeter is an integrating voltmeter. It never measures flux directly. It measures flux-linkage, the integral of voltage with respect to time. It is true that flux can be estim…
