1 T to 2.4 T – coil gap of a typical loudspeaker magnet; 1.5 T to 3 T – strength of medical magnetic resonance imaging systems in practice, experimentally up to 17 T [10] 4 T – strength of the superconducting magnet built around the CMS detector at CERN [11] 5.16 T – the strength of a specially designed room temperature Halbach array [12]
The first commercial plasma lamp was an ultraviolet curing lamp with a bulb filled with argon and mercury vapor developed by Fusion UV. That lamp led Fusion Lighting to the development of the sulfur lamp, a bulb filled with argon and sulfur that is bombarded with microwaves through a hollow waveguide. The bulb had to be spun rapidly to prevent ...
In 1882, Philip Diehl (inventor) was awarded a patent for a kind of induction incandescent lamp. [1]Nikola Tesla demonstrated wireless transfer of power to electrodeless lamps in his lectures and articles in the 1890s, and subsequently patented a system of light and power distribution on those principles.
[1] The plasma lamp was invented by Nikola Tesla, during his experimentation with high-frequency currents in an evacuated glass tube for the purpose of studying high voltage phenomena. [2] Tesla called his invention an "inert gas discharge tube". [3] The modern plasma lamp design was developed by James Falk and MIT student Bill Parker. [1] [4]
1 14 V / 3.78W Used on circuit boards for e.g. dash lights, gauge cluster backlights. Similar in size to W3W if with a T10 base. PC74 T1-3/4 (if removable) or fixed to holder [9] 1 14 V / 1.4W Used on circuit boards for e.g. dash lights, gauge cluster backlights.

Want to buy a new car in 2024? It's OK if you don't want to buy an EV. Here's how to find a good deal and save money on gas (and car insurance).
One tesla is equal to 10 4 gauss. Magnetic field drops off as the inverse cube of the distance ( 1 / distance 3 ) from a dipole source. Energy required to produce laboratory magnetic fields increases with the square of magnetic field.
