Geomagnetic instruments at National Museums Scotland

Abstract

In 1981, the sole book about historic geomagnetic instruments was by Anita McConnell. Using it as a timeline, the Royal Scottish Museum's temporary exhibition ‘The Earth is a Magnet’, was put on to coincide with an international congress held in Edinburgh that year. The curators were aware that this important story could be told only with borrowed material from a number of other collections and that, in some cases, crucial items no longer existed. Locating and borrowing such objects before the Internet proved tricky and time-consuming, but helped to form thinking about how the collections might grow. The paper will look at what there is, and something of what there is not, in the Scottish national collections.
