# Gauss (metric)

A Gauss is a unit of measure for magnetism.

## Description (Specifications)

A gauss is a metric system used to measure magnetic flux density ("magnetic induction"), relating force, length and electric current. One gauss is defined as one maxwell per square centimeter. It is used to conveniently measure weak fields, such as a small permanent magnet.

• It is equivalent to 0.00001 tesla.
• The standard abbreviation is Ga.
• The maxwell is the centimeter-gram-second (cgs) unit of magnetic flux.

### Examples of Gauss

• Terra's magnetic field: 0.5–0.6 Ga
• A galley refrigerator magnet: 100 Ga
• Junkyard electromagnet: 10,000 Ga
• Magnetic field of a large gas giant: 10,000 Ga
• Medical imaging scanner: 30,000 Ga
• Typical magnetic field observed on an ordinary star: 1,000,000 Ga (106 Ga)
• Magnetic field of radio pulsars (neutron stars): 1,000,000,000,000 Ga (1012 Ga)

### Term Usage Example

A Gauss Rifle utilizes artificially induced electromagnetic fields to propel 4 gram needle bullets to velocities of around 1500 meters per second.

## History & Background (Dossier)

Some species are able to perceive magnetic and electrical fields through their senses. This natural ability is known as Awareness: it is an analog of Vision and uses the nervous system as the sense organ. As a being moves within a field, the nervous system responds to the microcurrents which the field creates, and this information is processed by the brain in a similar way to how the skin senses wind or radiant heat. Awareness is mapped to the mental image using mind-generated false colors known as Mag and Lek. They are perceived as transparent vapors which do not illuminate or reflect. They are generally not blocked by intervening objects and can serve as a kind of xray vision.

The gauss was first defined as a unit of force on Terra prior to the foundation of the Terran Confederation: it is named for Carl Friedrich Gauss, a Terran mathematician and physicist born around -2743. Technologists found the gauss useful as the concept of the Technology Level and standardized ideas about sophont society development began to take form.[1]

The gauss, abbreviated as G or Gs, is the cgs unit of measurement of magnetic flux density (or "magnetic induction") (B). It is named after German mathematician and physicist Carl Friedrich Gauss.
