The transformation laws for electric and magnetic fields prescribed by special relativity (in MKS) for a particle traveling at a speed v are
(1)

(2)

(3)

(4)

(5)

(6)

where is relativistic gamma and c is the speed of light. These transformation laws can be combined into a single entity known as the field tensor,
(7)

In cgs, the field tensor is written
(8)

The dual electromagnetic field tensor is equivalent to replacing and , and gives the same transformation laws. In MKS,

and in cgs,
