Editing Tesla (unit) (section)

== 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 (unit)|newton]] (N), according to the [[Lorentz force law]].  That is, 
<math display=block>\mathrm{T = \dfrac{N{\cdot}s}{C{\cdot}m}}.</math>

As an [[SI derived unit]], the tesla can also be expressed in terms of other units.  For example, a [[magnetic flux]] of 1 [[weber (unit)|weber]] (Wb) through a surface of one square meter is equal to a [[magnetic flux density]] of 1 tesla.<ref name="brochure">''The International System of Units (SI), 8th edition'', [[BIPM]], eds.

<math display=block>\mathrm{T = \dfrac{Wb}{m^2}}.</math>

Expressed only in [[SI base unit]]s, 1 tesla is:
<math display=block>\mathrm{T = \dfrac{kg}{A{\cdot}s^2}},</math>
where A is [[ampere]], kg is [[kilogram]], and s is [[second]].<ref name="brochure" />

<!-- The additional derived unit equivalences may not be valuable, consider deleting these -->
Additional equivalences result from the derivation of coulombs from [[ampere]]s (A), <math>\mathrm{C = A {\cdot} s}</math>:
<math display=block>\mathrm{T = \dfrac{N}{A{\cdot}m}},</math>
the relationship between newtons and [[joule]]s (J), <math>\mathrm{J = N {\cdot} m}</math>:
<math display=block>\mathrm{T = \dfrac{J}{A{\cdot}m^2}},</math>
and the derivation of the weber from [[volt]]s (V), <math>\mathrm{Wb = V {\cdot} s}</math>:
<math display=block>\mathrm{T = \dfrac{V{\cdot}{s}}{m^2}}.</math>
