TeslaThe 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.
A smaller derived unit, the 1 T = 1 V · s · m -2 = 1 kg · s -2 · A -1 = 1 N · A -1 m -1 = 1 Wb · m -2
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 10 6 T to 10 8 T,
on a magnetar, 10 8 to 10 11 T,
maximum theoretical field strength for a neutron star, and therefore for any known phenomenon, 10 13 T.
Geophysics uses a unit of 1 γ = 10 -9 T.
