Demagnetizers and Remagnetizers
Demagnetizers and remagnetizers are used to remove a sample's magnetization or impart a laboratory acquired magnetization. They can be used in conjunction with the 2G magnetometer or spinner magnetometer for a wide variety of paleomagnetic and rock-magnetic applications.
