Geomagnetism Lab


Our Department houses world-class facilities for the undertaking of palaeomagnetic, archaeomagnetic, and rock magnetic experiments.  A key research focus is ancient geomagnetic field behaviour and this, combined with our rich history of instrument development, has led to the development of unique-in-the-world items such as our high frequency microwave palaeointensity system. These are backed up by a comprehensive suite of commercial instrumentation as shown below allowing us to engage in a broad range of academic and industrial research activities (e.g. archaeomagnetic dating, core orientation using viscous magnetisation, magnetic mineral characterisation).
