SPINNER MAGNETOMETER

Agico JR6A

PRIMARY USE

Archaeomagnetic Dating

The JR6A spinner magnetometer calculates the strength and direction of the magnetic field of a sample. These allow us to construct and compare to a record of the Earth's magnetic field over time to date a sample.

SIMPLE STATS

Sample Size: 2cm cube / 2.5cm cylinder

Sensitivity: 2.4e-6 A/m

Maximum Moment: 12,500 A/m

Hi/Lo speeds to accommodate fragile samples

PRIMARY MEASUREMENT

The direction of the magnetic record in a sample in the form of a vector made of three componenets:

Declination, the direction as if around a compass
Inclination, the degree of tilt up or down
Intensity, the strength of the field
