Visiting the Laboratory for Paleomagnetism and Environmental Studies

April at the Institute of Geophysics PAS has been designated the month of the Department of Magnetism. On this occasion, we cordially invite you to an internal Earth Day celebration on 22 April and a joint visit to the Laboratory of Palaeomagnetism and Environmental Studies. Please find below a detailed programme of the event.

11.00 Short welcome/ introduction – Rafał Szaniawski – the head of NM2 statutory project
1. Palaeomagnetic measurements – the record of magnetic field in rocks – room 317
  • The preparation of samples – presentation of the drill, the use of geological compass for sample orientation. The presentation of different samples and stages of the preparation process.
  • The presentation of processes of measurement of the magnetic remanence and demagnetization of samples 
  • Devices shown: cryogenic magnetometer, the furnace for thermal demagnetization, AF demagnetizer, accessories – amagnetic cage and pulse magnetizer
2. The magnetic anisotropy and its application - room 315
  • Anisotropy of magnetic susceptibility – the example of the measurement at KLY5 magnetic kappabridge
