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] .
He shows that the associated complementary electric and magnetic fields of electromagnetism travel through space, in the form of waves, at a constant velocity of 3.0 × 10 8 m/s. He also proposes that light is a form of electromagnetic radiation and that waves of oscillating electric and magnetic fields travel through empty space at a speed ...
The earliest Chinese literature reference to magnetism lies in a 4th-century BC book called The Book of the Devil Valley Master: "When the people of Cheng go out to collect jade, they carry a south-pointer with them so as not to lose their way." [9]: 110 [10] Electric catfish are found in tropical Africa and the Nile River.
Through the 1920s and 30s a number of theoretical problems related to the device were considered by scientists including Rolf Wideroe, [3] [4] Ernest Walton, and Max Steenbeck. [5] The first working betatron was constructed by Donald Kerst at the University of Illinois Urbana-Champaign in 1940.
Top: The charge is at rest in frame F, so this observer sees a static electric field.An observer in another frame F ′ moves with velocity v relative to F, and sees the charge move with velocity −v with an altered electric field E due to length contraction and a magnetic field B due to the motion of the charge.
Of all the mythical monsters, Frankenstein is probably the most famous. Brought to life by author Mary Shelley in the 1818 novel by the same name, the mythical monster was said to have been ...
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 ...
JEREMY: "This is the biggest fish of my South American fishing career. A river monster as deadly as any beast of folklore." Like always, Jeremy tossed the fish back in the water.
