A Bitter electromagnet or Bitter solenoid is a type of electromagnet invented in 1933 by American physicist Francis Bitter used in scientific research to create extremely strong magnetic fields. Bitter electromagnets have been used to achieve the strongest continuous manmade magnetic fields on earth―up to 45 teslas, as of 2011. [2]
The largest magnetic fields produced in a laboratory occur in particle accelerators, such as RHIC, inside the collisions of heavy ions, where microscopic fields reach 10 14 T. [50] [51] Magnetars have the strongest known magnetic fields of any naturally occurring object, ranging from 0.1 to 100 GT (10 8 to 10 11 T). [52]
The magnetic flux density does not measure how strong a magnetic field is, but only how strong the magnetic flux is in a given point or at a given distance (usually right above the magnet's surface). For the intrinsic order of magnitude of magnetic fields, see: Orders of magnitude (magnetic moment). Note:
These magnetic fields are a hundred million times stronger than any man-made magnet, [11] and about a trillion times more powerful than the field surrounding Earth. [12] Earth has a geomagnetic field of 30–60 microteslas, and a neodymium-based, rare-earth magnet has a field of about 1.25 tesla, with a magnetic energy density of 4.0 × 10 5 J/m 3.
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 ...
Ferrofluid on glass, with a rare-earth magnet underneath. A rare-earth magnet is a strong permanent magnet made from alloys of rare-earth elements.Developed in the 1970s and 1980s, rare-earth magnets are the strongest type of permanent magnets made, producing significantly stronger magnetic fields than other types such as ferrite or alnico magnets.
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; 1200 T – the field, lasting for about 100 microseconds, formed using the electromagnetic flux-compression ...
The magnetosphere of Jupiter is the cavity created in the solar wind by Jupiter's magnetic field.Extending up to seven million kilometers in the Sun's direction and almost to the orbit of Saturn in the opposite direction, Jupiter's magnetosphere is the largest and most powerful of any planetary magnetosphere in the Solar System, and by volume the largest known continuous structure in the Solar ...
