The MicroMag™ 2900 Series AGM is a powerful system for measuring the magnetic properties of a vast range of materials. Extremely high sensitivity (10 nemu rms—corresponding to less than 50 pg of iron) and speed of measurement
(10 ms/point), combined with compact design and ease of use result in a system as well-suited to production test and quality control as it is to basic research.
The MicroMag™ system accommodates all types of samples (up to 5 × 5 × 2 mm: 200 mg mass): solids, ultra thin films, powders, liquids and even slurries. Applications include measurements of magnetic recording
media, MRAM, GMR and TMR heads, amorphous metals, rare earth magnets, high temperature superconductors, nanomagnets, weak ferrofluids, biological specimens, toner material, magneto-optic devices, paleomagnetic samples and very weak diamagnetic
and paramagnetic materials.
Included in the system are a modern personal computer, comprehensive Windows® based operating software and color printer. The MicroMag™ is available with a 2 in or 4 in laboratory electromagnet, each powered by a fast four-quadrant
power supply, all under computer control.

How an AGM works (1:13)
Combination system also available—Major components of the AGM system, including system operating software, are fully compatible with the MicroMag™ 3900 Series VSM, permitting a combination of the techniques to serve an even
greater range of applications. The integrated design of the combination VSM/AGM system is an economic way of having maximum measurement capability.
