Tesla

The compound derived SI unit, the tesla, abbreviated as T, is the unit for the magnetic flux density or the magnetic inductivity[?]. The unit was named in the honor of the Yugoslavian Serb 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

Another smaller derived unit for the magnetic flux density which was once used is gauss = 10^-4 T.

• 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,
• on a neutron star 10¹⁰ T to 10¹² T.
• on a magnetar, 10¹² to 10¹⁵.
• maximum field strength possible for any known phenomenon, 10¹⁷

Geophysics uses an unit 1 γ = 10 ^-9 T.
