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] .
1838 the Cooke and Wheatstone telegraph becomes the first commercial telegraph in the world when it is installed on the Great Western Railway. 1837 – Samuel Morse develops an alternative electrical telegraph design capable of transmitting long distances over poor quality wire. He and his assistant Alfred Vail develop the Morse code signaling ...
The Italian Guglielmo Marconi transmits wireless telegraph messages by electromagnetic waves over a distance of five kilometers. 1898 The Danish physicist Valdemar Poulsen creates the world's first magnetic recording and reproduction, using a 1 mm thick steel wire as a magnetizable carrier.
Michael Faraday (/ ˈ f ær ə d eɪ,-d i /; 22 September 1791 – 25 August 1867) was an English chemist and physicist who contributed to the study of electrochemistry and electromagnetism.
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.
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 ...
A.D. 79: Mount Vesuvius, Italy. Mount Vesuvius has erupted eight times in the last 17,000 years, most recently in 1944, but the big one was in A.D. 17. One of the most violent eruptions in history ...
Electricity and Magnetism is a standard textbook in electromagnetism originally written by Nobel laureate Edward Mills Purcell in 1963. [1] Along with David Griffiths ' Introduction to Electrodynamics , this book is one of the most widely adopted undergraduate textbooks in electromagnetism . [ 2 ]
