Gauss (unit)

The gauss (symbol G) is the CGS unit used to measure magnetic fields. One gauss is defined as one maxwell per square centimeter. The tesla (symbol T) is the SI derived unit used to measure the strength of magnetic fields. There are 10,000 (104) gauss in one tesla.

The unit is named in honor of the German mathematician and physicist Carl Friedrich Gauss.

 Example values 
 10−9–10−8 gauss – the magnetic field of the human brain
 0.31–0.58 gauss – the Earth's magnetic field at its surface
 25 gauss – the Earth's magnetic field in its core 
 50 gauss – a typical refrigerator magnet
 100 gauss – a small iron magnet
 600-70,000 gauss – a medical magnetic resonance imaging machine 
 1012–1013 gauss – the magnetic field on the surface of a neutron star
 4×1013 gauss – the quantum electrodynamic threshold
 1015 gauss – the magnetic field of some newly created magnetars
 1017 gauss – the upper limit to neutron star magnetism; no known object in the universe can generate a stronger magnetic field
