On the Magnetic Properties of Construction Materials for Magnetic Observatories

The installation and development of a magnetic observatory can require additional studies the properties construction materials for pavilions measurement pillars, as well environmental conditions, including, first all, surrounding rocks. In some cases, detailed susceptibility be necessary. To date, these procedures have only briefly been described in existing manuals guides. With new materials, with increase number observatories, need such has risen even more. This article is focused on results are presented based our experience deployment observatories stations Russia abroad. An overview different presented. A kappametry method its application to described, tests performed rocks vicinity an provided. Finally, recommendations given.
