Definitions[change | change source]
Using only the seven base SI units, the definition of a tesla is:
Using other SI derived units, a tesla is also equal to:
The units used are:
Example values[change | change source]
- 3.1×10−5–5.8-5 T – the Earth's magnetic field at its surface
- 5×10-3 T – the strength of a typical refrigerator magnet
- 0.3 T – the strength of solar sunspots
- 1.25T – the strength of the surface of a neodymium magnet
- 1.5−3 T – strength of medical magnetic resonance imaging systems
- 4 T – strength of the superconducting magnet built around the CMS detector at CERN
- 13 T – strength of ITER fusion reactor
- 16 T – magnetic field strength required to levitate a frog as part of an Ig Nobel Prize winning project.
