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] .
Specifically, to count as a legitimate view, a user must intentionally initiate the playback of the video and play at least 30 seconds of the video (or the entire video for shorter videos). Additionally, while replays count as views, there is a limit of 4 or 5 views per IP address during a 24-hour period, after which point, no further views ...
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.

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.
Fair warning, it almost hurts to look at this photo of a woman sitting on a subway that's going viral. Sitting with your legs nicely crossed is one thing, but this woman somehow managed to twist ...
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.
