It is a derived unit of the International System of Units, the modern form of the metric system. One tesla is equal to one weber per square metre. The unit was announced during the General Conference on Weights and Measures in 1960 and is named in honour of Nikola Tesla. The strongest fields encountered from permanent magnets are from Halbach spheres which can be over 4.5 T. The strongest field trapped in a laboratory superconductor as of July 2014 is 17.6 T.〔http://www.magnet.fsu.edu/mediacenter/factsheets/records.html〕 The record magnetic field has been produced by scientists at the Los Alamos National Laboratory campus of the National High Magnetic Field Laboratory, the world's first 100-tesla, non-destructive magnetic field. == Definition == A particle, carrying a charge of 1 coulomb, and passing through a magnetic field of 1 tesla, at a speed of 1 metre per second, perpendicular to said field, experiences a force with magnitude 1 newton, according to the Lorentz force law. As an SI derived unit, the tesla can also be expressed as : (The last equivalent is in SI base units).〔''The International System of Units (SI), 8th edition'', BIPM, eds.
