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.
