Origin
The oersted, also known as oersted 1 , is named in honor of the physicist and chemist Hans Christian Oersted born in Rudkobing , Denmark one 14 as August as 1777 and died in Copenhagen , Denmark one 9 as March as 1851 . Oersted, distinguished by studies carried out on electromagnetism , demonstrating together with André Marie Ampère , that when an electric current circulates through an electrical conductor , a magnetic field arisesaround said conductor, knowing from then on this phenomenon, as a magnetic field .
Definition
The oersted is equivalent to a magnetic field produced in a vacuum and at a distance of 1 cm , per the magnetic pole unit. It has replaced the gauss , today reserved for measuring the intensity of magnetic induction .
Formulation
1 Oe = 103 / 4π A · m -1
Equivalence with the unity of the International System
In the International System of Units the unit of magnetic field intensity 2 is the ampere per meter .

Terminology Note
This unit belonging to the Cegesimal System of Units known by the acronym CGS is named after Hans Christian Oersted . In units of measurement whose designation comes from a person’s own name, the first letter of the symbol is written with a capital letter (Oe), while its name always begins with a lowercase letter (oersted), except when it starts a phrase or a title.
