Tesla The tesla (symbol T ) is the compound derived SI unit of magnetic flux density or magnetic inductivity. At the Conference General des Poids et Mesures (CGPM ) in Paris in 1960 , the unit was named in honor of the Serbian -American inventor and electrical engineer Nikola Tesla who made several important contributions to the field of electromagnetism .
1 T = 1 V · s · m -2 = 1 kg · s -2 · A -1 = 1 N · A -1 m -1 = 1 Wb · m -2
A smaller derived unit, the gauss = 10-4 T, was once used.
In outer space the magnetic flux density is between 10-10 T and 10-8 T,
in the Earth 's magnetic field at latitude of 50° is 2 · 10-5 T and on the equator at a latitude of 0° is 3.1 · 10-5 T,
in the magnetic field of a huge horseshoe magnet 0,001 T,
in a sunspot 10 T,
strongest continuous magnetic field yet produced in a laboratory (Florida State University 's National High Magnetic Field Laboratory in Tallahassee , USA, September 2003), 25 T. It is possible to generate much stronger fields in a laboratory in a pulse lasting a few milliseconds,
on a neutron star 106 T to 108 T,
on a magnetar , 108 to 1011 T,
maximum theoretical field strength for a neutron star, and therefore for any known phenomenon, 1013 T.
Geophysics uses a unit of 1 γ = 10 -9 T.
