Kletetschka*Catholic University of America, Physics Department, Washington DC, 20064, USA ; Institute of Geology, Academy of Sciences of the Czech Republic, Czech Republic; GSFC/NASA, 8800 Greenbelt Rd, Code 691, Greenbelt, USA This investigation tests whether fracture formation in cryo-preserved ice containing bodies could be affected by alternating magnetic field. The experiment was done on ion containing water inside a plastic container. Magnetism was used to stabilize/balance the pressure exerted during the freezing process. First we tested whether steady application of strong magnetic field has any positive effect on fracture formation, namely, whether a continuous magnetic field exposure can induce any specific fracture pattern. Using the direct current in the electromagnet the effect on fractures was negligible. However, when freezing the water by liquid nitrogen exposed to the alternating current generated magnetic field, we did not observed any fracture formation. When alternating magnetic field was absent, the water frozen by liquid nitrogen contained multiple radial fractures. Our hypothesis is that rapidly changing magnetic field generates eddy currents inside the water and this shifts the phase transition between the liquid water and solid forming ice, allowing stress relieve within the new ice. Our observation suggests to use alternating magnetic field chambers during the cryopreservation procedure because fractures are one of the critical concerns of cryonics.
