Paleomagnetics Lab

(Lab located in 250 Morrill South)

The Paleomagnetics Lab equipment is dedicated to the research of core samples from around the globe. Performed tests help us to better understand magnetism in these sites and also to find the declination/inclination of the magnetic fields in the paleoenvironments.


Cryogenic Magnetometer

_____________________________________

The cryogenic magnetometer is cooled by a process which circulates liquid helium through superconducting elements. This instrument measures magnetic orientation (x,y,z) of rock core samples and can measure magnetic intensity samples as low as 10e-8 emu/cc. The data is then transfered directly to the PAcquire program on the computer.

Thermal Demagnetizer
  

_____________________________________________________________

The ASC Scientific Thermal Demagnetizer can reach temperatures of 700 C and is used to eradicate magnetizations with low Curie Temperatures in a field-free space. The red coil seen protruding from the end can either be used to completely eliminate all magnetic fields in the cylander or to apply a field which can test the properties of the sample.

Alternating-field Demagnetizer
  

_____________________________________

The Molspin Alternating-Field Demagnetizer is used to "magnetically clean" samples by subjecting them to decreasing alternating magnetic fields. The instrument is capable of producing fields up to 999 oersteds.
