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] .
The facility is notable for containing what is believed to be the world's largest Marx generator, which was originally created to help test lightning insulation in military aircraft. The facility has several huge Tesla coils on the facility grounds, some of which range over 20 stories in height.
The current world's largest Tesla coil is a 130,000-watt unit built by Greg Leyh and Eric Orr, part of a 38-foot-tall (12 m) sculpture titled Electrum owned by Alan Gibbs and currently residing in a private sculpture park at Kakanui Point near Auckland, New Zealand.
In 2007, a magnet with windings of YBCO achieved a world record field of 26.8 T. [13] The US National Research Council has a goal of creating a 30-tesla superconducting magnet. Globally in 2014, almost six billion US dollars worth of economic activity resulted from which superconductivity is indispensable.
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.
An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. Electromagnets usually consist of wire (likely copper) wound into a coil. A current through the wire creates a magnetic field which is concentrated along the center of the coil. The magnetic field disappears when the current is turned off.
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.
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]
