Guinness World Records

The most powerful electric current
The most powerful electric current was generated at the Los Alamos Science Laboratory, New Mexico, USA. With a simultaneous discharge of 4032 capacitors, combined into a Zeus supercapacitor, within a few microseconds, they give twice as much electric current than that generated by all the power plants of the Earth.

Highest voltage
On May 17, 1979, at the National Electrostatics Corporation, Oak Ridge, Tennessee, USA, the highest electric potential difference was obtained in the laboratory. It amounted to 32 ± 1.5 million V.

Highest measured frequency
The highest frequency that the naked eye perceives is the vibrational frequency of yellow-green light, equal to 520.206 808 5 terahertz (1 terahertz - one million million hertz), corresponding to the transition line 17 - 1 P (62) iodine-127.
The highest frequency measured using instruments is the green light vibration frequency, equal to 582.491 703 THz for the b21 component of R (15) 43 - 0 of the iodine-127 transition line. By a decision of the General Conference of Weights and Measures, adopted on October 20, 1983, for the precise expression of meter (m) using the speed of light (c), it is established that “meter is the path traveled by light in vacuum for a time interval equal to 1/299792458 seconds ". As a result, the frequency (f) and wavelength (λ) are related by the dependence f · λ = c.

The most powerful permanent field
The most powerful constant field of 35.3 ± 0.3 Tesla was obtained at the National Magnetic Laboratory named after Francis Bitter at the Massachusetts Institute of Technology, USA, May 26, 1988. A hybrid magnet with holmium poles was used to obtain it. Under its influence, the magnetic field created by the heart and brain was enhanced.
The weakest magnetic field was measured in a shielded room in the same laboratory. Its value was 8 · 10–15 Tesla. It was used by Dr. David Cohen to study the extremely weak magnetic fields created by the heart and brain.

The heaviest magnet
The heaviest magnet in the world has a diameter of 60 m and weighs 36 thousand tons. It was made for a 10 TeV synchrophasotron installed at the Joint Institute for Nuclear Research in Dubna, Moscow Region.

The largest electromagnet
The world's largest electromagnet is part of the L3 detector used in experiments at the Large Electron-Positron Collider (LEP) of the European Council for Nuclear Research, Switzerland. An octagonal electromagnet consists of a yoke made of 6400 tons of low-carbon steel and an aluminum coil weighing 1100 tons. Yoke elements, weighing up to 30 tons each, were made in the USSR. The coil, made in Switzerland, consists of 168 turns, secured by electric welding on an octagonal frame. A current of 30 thousand A, passing through an aluminum coil, creates a magnetic field with a capacity of 5 kilogauss. The dimensions of the electromagnet, exceeding the height of a 4-story building, are 12x12x12 m, and the total weight is 7810 tons. It took more metal to produce it than to build the Eiffel Tower.

The most durable light bulb
An average incandescent light burns for 750 ... 1000 hours. There is evidence that a five-watt lamp with carbon filament, manufactured by Shelby Electric and recently demonstrated by Mr. Burnell at the Fire Department of Livermore, California, USA, gave light in 1901

The brightest light
The brightest sources of artificial light are laser pulses, which were generated at the Los Alamos National Laboratory, New Mexico, USA, in March 1987 by Dr. Robert Graham. The flash power of ultraviolet light lasting 1 picosecond (1 · 10–12 s) was 5 · 1015 W.
The most powerful constant-light source is a high-pressure argon arc lamp with a power consumption of 313 kW and a luminous intensity of 1.2 million candela, manufactured by Vortek Industries in Vancouver, Canada, in March 1984.
The most powerful spotlight was produced during the Second World War, in 1939 ... 1945, by General Electric. It was developed at the Hearst Research Center, London. With a power consumption of 600 kW, it gave an arc brightness of 46,500 cd / cm2 and a maximum beam intensity of 2,700 million cd from a parabolic mirror with a diameter of 3.04 m.
