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 [update] .
It is the only such facility in the US, [1] and is among twelve [2] high magnetic facilities worldwide. The lab is supported by the National Science Foundation and the state of Florida, and works in collaboration with private industry. The lab holds several world records for the world's strongest magnets, including highest magnetic field of 45. ...

This gives the Nd 2 Fe 14 B compound a high saturation magnetization (J s ≈ 1.6 T or 16 kG) and a remanent magnetization of typically 1.3 teslas. Therefore, as the maximum energy density is proportional to J s 2 , this magnetic phase has the potential for storing large amounts of magnetic energy ( BH max ≈ 512 kJ/m 3 or 64 MG·Oe ).
An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. Electromagnets usually consist of wire wound into a coil. A current through the wire creates a magnetic field which is concentrated in the hole in the center of the coil. The magnetic field disappears when the current is turned off.
Ancient world Investigation into electromagnetic phenomena began about 5,000 years ago. There is evidence that the ancient Chinese , [ 1 ] Mayan , [ 2 ] [ 3 ] and potentially even Egyptian civilizations knew that the naturally magnetic mineral magnetite had attractive properties, and many incorporated it into their art and architecture.

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.
