The lab holds several world records for the world's strongest magnets, including highest magnetic field of 45.5 Tesla. [3] For nuclear magnetic resonance spectroscopy experiments, its 33-short-ton (29-long-ton; 30 t) series connected hybrid (SCH) magnet broke the record during a series of tests conducted by MagLab engineers and scientists on 15 ...
A world record of high magnetic field (31.35 Teslas) was achieved in 1987 within a collaboration including the CEA, the CNRS and the MPI. In 1990 a new 24 MW power supply was set into operation that led to the development of a new generation of magnet that reached progressively 33 T.
A magnetic field is a vector field, but if it is expressed in Cartesian components X, Y, Z, each component is the derivative of the same scalar function called the magnetic potential. Analyses of the Earth's magnetic field use a modified version of the usual spherical harmonics that differ by a multiplicative factor.
35.4 T – the current (2009) world record for a superconducting electromagnet in a background magnetic field [19] 45 T – the current (2015) world record for continuous field magnets [19] 97.4 T – strongest magnetic field produced by a "non-destructive" magnet [20] 100 T – approximate magnetic field strength of a typical white dwarf star
Magnetic induction B (also known as magnetic flux density) has the SI unit tesla [T or Wb/m 2]. [1] One tesla is equal to 10 4 gauss. Magnetic field drops off as the inverse cube of the distance ( 1 / distance 3 ) from a dipole source. Energy required to produce laboratory magnetic fields increases with the square of magnetic field. [2]
By experimentally applying a certain velocity field to a small magnetic field, one can observe whether the magnetic field tends to grow (or not) in response to the applied flow. If the magnetic field does grow, then the system is either capable of dynamo action or is a dynamo, but if the magnetic field does not grow, then it is simply referred ...
The magnetic moment of an object is an intrinsic property and does not change with distance, and thus can be used to measure "how strong" a magnet is. For example, Earth possesses an enormous magnetic moment, however we are very distant from its center and experience only a tiny magnetic flux density (measured in tesla ) on its surface.
During the transition, Earth's magnetic field declined to a minimum of 5% of its current strength, and was at about 25% of its current strength when fully reversed. This reduction in geomagnetic field strength resulted in more cosmic rays reaching the Earth , causing greater production of the cosmogenic isotopes beryllium-10 and carbon-14 , a ...
