-In his original publication in 1865,[(Maxwell)] **James Clerk Maxwell** listed 20 equations, which were split for each orthogonal coordinates (hence the large number of equations). These equations were later rationalised by **Oliver Heaviside**, who expressed them in a [[vector]] form which is know today.[(Heaviside>[[https://macsphere.mcmaster.ca/bitstream/11375/14746/1/fulltext.pdf|Oliver Heaviside, Electromagnetic theory, Vol. I, 1893, Ernest Benn Limited]])] There are four basic electromagnetic equations, supplemented by additional [[constitutive relations]], as well as expressions of energy conservation, and force.+In his original publication in 1865,[(Maxwell)] **James Clerk Maxwell** listed 20 equations, which were split for each orthogonal coordinates (hence the large number of equations).
