What are Tesla and Gauss units? Origin and applications in the field of magnetism.

The units of Gauss and Tesla are units of measure that help us calculate the magnetic flux and force of the magnets.

Gauss Physics - What is the Gauss unit?

A magnetic flux or magnetic flux density can be described in the Gauss unit. The field strength is given in Gauss or Tesla. The strength of the permanent magnet is defined by remanence. Consequently, Tesla is also a unity described by remanence. The Gauss unit is composed of the CGS system, i.e. it is based on the most natural and basic units that describe the magnetic flux density in a certain proportion. The CGS system uses the unit of length in centimeters (cm), the mass in grams (g) and the unit of time in seconds (s).


Tesla Physics - What is Tesla Unity?

A magnetic flux can also be described by the Tesla unit. Much of what has been described above also applies to the Tesla unit. Tesla is 10,000x larger than Gauss (Gauss = Tesla / 10,000). The strength of a magnet is sometimes described incorrectly in Tesla. Because a magnetic field or magnetic flux density does not exactly correspond to a magnetic field. The difference with Gauss is that Tesla consists of units of the SI system and not of the CGS system. The difference of the CGS system is that the unit of length is used in meters (m), instead of centimeters, and the unit of measurement in kilograms (kg) instead of grams (g). The time in seconds is also retained in the SI system.

Tesla vs Gauss


The inventor Johann Carl Friedrich Gauss

Gauss lived in the 19th century and was a mathematician. In 1831, he made a decisive contribution to the development of magnetometers to measure the strengths of the magnetic field. Johann Carl Friedrich Gauss made very important discoveries in the fields of astronomy, physics and mathematics. Among his inventions is the bell curve, the most famous of his inventions. This is used in statistics. With random measurement values, the Gauss bell can be properly distributed.


Inventor Nikola Tesla

Tesla lived between the nineteenth and twentieth centuries, which deals very deeply with electromagnetism. As an electronic engineer, he made important discoveries in the field of alternating current. Tesla is the reason AC is used in today's power technology and not in DC technology, which was invented by Edison. For this, for example, the transformer, which generates alternating voltage.


Use of Gauss and Tesla units

Magnetic flux density and magnetic flux can be calculated from the force of moving loads. Therefore, Gauss and Tesla units are not basic units.

The following applies to Tesla physics:

1T = 1 N / A⋅m

According to the formula, a Tesla equals one newton (N) between amps (A) per meter (m). Let's take a closer look at this statement. Therefore, a Tesla corresponds to a magnetic flux density exerted by 1 Newton on a conductor that is 1 m long and through which a current of 1A flows.

Magnetic flux density B can be used to calculate magnetic field strength H. For this, magnetic flux density is divided by material permeability (μ) and vacuum (μ0):

H = B / μ⋅μ0

In Gauss's physics, the same formulas are expected.
