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] .
Chinese manufacturers have become a dominant force in neodymium magnet production, based on their control of much of the world's rare-earth mines. [ 10 ] The United States Department of Energy has identified a need to find substitutes for rare-earth metals in permanent magnet technology and has funded such research.
Cutaway diagram of the International Thermonuclear Experimental Reactor (ITER) the largest tokamak in the world, which began construction in 2013 and is projected to begin full operation in 2035. It is intended as a demonstration that a practical fusion reactor is possible, and will produce 500 megawatts of power.
While at MIT, he developed the Bitter electromagnet which was/is the most powerful electromagnet design. He established a magnet laboratory in 1938, where he built a solenoid magnet that produced a constant field of 100,000 gauss (10 teslas). [citation needed]

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.
The 500-million download threshold for free applications has been established to maintain the list's manageability and focus on the most widely distributed apps. It's worth noting that many of the applications in this list are distributed pre-installed on top-selling Android devices [ 2 ] and may be considered bloatware by some people because ...
The shape of the magnet was originally created as a replacement for the bar magnet as it makes the magnetic field stronger for a magnet of comparable strength. [5] A horseshoe magnet is stronger because both poles of the magnet are closer to each other and in the same plane which allows the magnetic lines of flux to flow along a more direct path between the poles and concentrates the magnetic ...
