What Does AF Stand For?
AF stands for Alternating Field Demagnetization
AF, or Alternating Field Demagnetization, is a geophysical technique used to remove remanent magnetization from rock or sediment samples. This method involves subjecting samples to alternating magnetic fields, which gradually decrease in intensity, thereby demagnetizing the samples while preserving their original magnetic properties. AF demagnetization is commonly employed in paleomagnetic studies to isolate the primary magnetic signal from overprinting effects, facilitating more accurate interpretations of historical geomagnetic data.
