Definition:Tesla

Definition

The tesla is the SI unit of magnetic flux density.

It is defined as being:

The magnetic flux density that generates a force of $1$ newton on an electrical conductor carrying $1$ ampere of electric current.

Thus it is equal to $1$ weber of magnetic flux per square metre.

Symbol

$\mathrm T$

The symbol for the tesla is $\mathrm T$.

Its $\LaTeX$ code is \mathrm T .

Base Units

The SI base units of the tesla are:

$\mathrm T := \mathrm {kg} \, \mathrm s^{-2} \mathrm A^{-1}$

where:

$\mathrm {kg}$ denotes kilogram

$\mathrm A$ denotes amperes

$\mathrm s$ denotes seconds (of time).
