Definition

A particle, carrying a charge of one coulomb (C), and moving perpendicularly through a magnetic field of one tesla, at a speed of one metre per second (m/s), experiences a force with magnitude one newton (N), according to the Lorentz force law. That is, T = N ⋅ s C ⋅ m. {\displaystyle \mathrm {T={\dfrac {N{\cdot }s}{C{\cdot }m}}}.}

As an SI derived unit, the tesla can also be expressed in terms of other units. For example, a magnetic flux of 1 weber (Wb) through a surface of one square meter is equal to a magnetic flux density of 1 tesla. That is, T = W b m 2. {\displaystyle \mathrm {T={\dfrac {Wb}{m^{2}}}}.}

Expressed only in SI base units, 1 tesla is: T = k g A ⋅ s 2, {\displaystyle \mathrm {T={\dfrac {kg}{A{\cdot }s^{2}}}},} where A is ampere, kg is kilogram, and s is second.

Additional equivalences result from the derivation of coulombs from amperes (A), C = A ⋅ s {\displaystyle \mathrm {C=A{\cdot }s} }: T = N A ⋅ m, {\displaystyle \mathrm {T={\dfrac {N}{A{\cdot }m}}},} the relationship between newtons and joules (J), J = N ⋅ m {\displaystyle \mathrm {J=N{\cdot }m} }: T = J A ⋅ m 2, {\displaystyle \mathrm {T={\dfrac {J}{A{\cdot }m^{2}}}},} and the derivation of the weber from volts (V), W b = V ⋅ s {\displaystyle \mathrm {Wb=V{\cdot }s} }: T = V ⋅ s m 2. {\displaystyle \mathrm {T={\dfrac {V{\cdot }{s}}{m^{2}}}}.} The tesla is named after Nikola Tesla. As with every SI unit named for a person, its symbol starts with an upper case letter (T), but when written in full, it follows the rules for capitalisation of a common noun; i.e., tesla becomes capitalised at the beginning of a sentence and in titles but is otherwise in lower case.
