Relation Between Gauss and Tesla - A Complete Guide

What is Gauss?

Gauss is the unit of magnetic induction in the CGS system. It is named after Carl Friedrich Gauss, a famous German physicist.

The base unit of Gauss is, $1 {cm}^{- 1 / 2} g^{1 / 2} s^{- 1}$

1 gauss is defined as 1dyne of force which exerts on a charge of 1emu which moves in velocity of 1cm/s in the magnetic field perpendicularly.

What is Tesla?

Tesla is a unit of magnetic field intensity or magnetic induction. In other words, the SI unit of magnetic induction is Tesla or it. It is usually denoted by T. This unit is named after Nikola Tesla, the famous American physicist.

Tesla $= K g s^{- 2} A^{- 1}$

1 Tesla is defined as the intensity of a magnetic field which generates a force of 1Newton per current of 1Ampere and a conductor of one meter.

So 1 Tesla is equal to 1N of force which exerts on coulomb of charge of 1C which moves in velocity of 1m/s in the magnetic field perpendicularly.

Relation Between Gauss and Tesla

We are all aware of the attraction and repulsion forces upon a charge entering an electric or magnetic field. Now suppose some moving charge particle enters into the magnetic field then the size of the force experienced or acting on that charged particle is called the intensity of magnetic field or sometimes we will call it Magnetic Induction, which can be calculated using Lorentz as:

$F = q (V \times B)$

or, $F = q V B Sin θ$ (1)

Here, F = Lorentz force(F)
$q =$ magnitude of the charge on moving particle (C)
$V =$ velocity of moving particle
$B =$ magnitude of magnetic field intensity
$& θ =$ angle between the velocity vector and magnetic field vector.
From equation (1), we can derive, the magnitude of magnetic field intensity as,

$B = F / q V$
And, the units of this magnetic field intensity are Gauss or Tesla, depending upon the units system considered for the calculation and both the units are also interrelated to each other.

This relation between Gauss and Tesla helps us convert from one unit to another and vice versa and will be proved to be convenient while doing calculations.

Conversion of Gauss to Tesla or Tesla to Gauss

The Conversion of Gauss to Tesla or Tesla to Gauss is quite simple as both are directly proportional. Tesla is a big unit that can be converted into small units.

1 tesla is equal to how many gauss?

1Tesla is 1N of force which exerts on coulomb of charge of 1C which moves in velocity of 1m/s in the magnetic field perpendicularly.

1Tesla = 1N /(1C * 1m/s)

We know that

1N = 10⁵ dyne

1C = 10^-1 emu

1m/s = 10² cm/s

1Tesla = 10⁵ dyne/(10^-1 emu*10²cm/s)

1Tesla = 10⁴dyne/(emu*cms)

1Tesla = 10⁴ gauss

Therefore, one tesla is equal to 10⁴gauss.

Conversion of 1 gauss to tesla:

1 gauss is equal to 10^-4 Tesla.

4. Convert 10G to T

10gauss = 0.001 Tesla

5. Which is the preferred conversion 1.Gauss to tesla 2.Tesla to gauss

Tesla to gauss

Solution

Gauss to tesla is usually preferred because the gauss(CGS) system is the measuring system for only 3units length, mass, time. But the Tesla (SI) is the measuring system for not only 3units it has around 7units. So gauss which has only 3dimensional measuring units is usually preferred than tesla units for easy measurement as this SI unit will lead to 4dimension.
