SI 1 kg (A·s ²) = 1 Wb/m ²

Tesla (T) is a derived SI-UNIT for the magnetic flow density or induction. The unit became in the year 1960 on the Conférence general of thePoids et Mesures (CGPM) in Paris after Nikola Tesla designated.

1 T: = 1 V·s/m ² = 1 N/(A·m) = 1 stock /m ² = 1 kg/(A·s ²)

in the CGS system,above all still in theoretical physics , is the appropriate unit Gauss = 10 is used -4 T. Geophysics used also the unit γ.

1 γ: = 10 -9 T = 1 NT

of examples of different magneticFlow densities in nature and in the technology:

  • in space the magnetic flow density between 10,-10 T and 10 -8 T , in
  • the earth's magnetic field amounts to to 50. Degree of latitude 2 · 10 -5 T, at the equator 3,1 · 10 -5 T
  • thatMagnetic field of a large horseshoe magnet amounts to approximately 0.001 T,
  • the magnetic field of a Kernspintomographen for application at humans up to 7,2 T (strongest European Kernspintomograf in Magdeburg).
  • the magnetic field of at present strongest superconducting magnets in the NMR spectroscopy (900 MHz spectrometers) 21 T
  • a typical sunspot 45 T
  • have 0.25 T the strongest constant magnetic field, which was produced by a hybrid magnet (resistiv + superconducting) in a laboratory the Florida State University in Tallahassee, Florida. It is possible, substantially stronger fields for fewTo produce milliseconds, for example by intensive laser irradiation -- 34,000 T for 10 HP (source [1])
  • on a neutron star 10 6 T to 10 8 T,
  • on a Magnetar 10 8 to 10 11 T,
  • maximum theoretical field strength oneNeutron star, and thus for the largest well-known phenomenon, 10 13 T.
