At the center of a busy traffic interchange of Elephant and Castle sits a gleaming stainless steel box that has perplexed south Londoners for decades. This late-brutalist masterpiece everyone forgot about was originally created to get the proletariat jazzed about the arts. This massive Brazilian church is built like an angular, technicolor pyramid left by Mayans from the future.
The building was designed by Brutalist architect Rodney Gordon in 1959 to house, quite fittingly, a London Underground electrical substation.
This design change is at least part of the reason why the building has a decidedly modern appearance that belies its true age. Although a thorough redevelopment of the Elephant and Castle area is in the works, the Faraday Memorial's status as a grade II listed building ensures that it will not be demolished and will instead be moved to a new site if necessary.

Eddy current testing began largely as a result of the English scientist Michael Faraday's discovery of electromagnetic induction in 1831. Beginning in 1933, in Germany, while working for the Kaiser-Wilhelm-Institute, Professor Friedrich Forster adapted eddy current technology to industrial use, developing instruments for measuring conductivity and for sorting mixed-up ferrous components. It's very likely you woke up this morning in a Faraday cage, made your breakfast in another one, and drove one to work. The concept of a Faraday cage is logically attributed to Michael Faraday, a 19th century pioneer in the field of electromagnetic energy.
The important concept to remember is that a Faraday cage acts as a shield against the effects of electromagnetic energy.


Few consumers of electronic products would ever ask the sales clerk for a Faraday cage, but designers and engineers understand the importance of electromagnetic shielding very well. The concept of a faraday cage is often used in science fiction as a way to defeat some kind of weapon or power.
It is a metallic enclosure and it anticipates the entry or escape of an electromagnetic area. I'd like to ask where is it possible to find a truck with an F-shield to make, forwarding from Europe to Russia?
If I suspend a water tight container in the middle of a 10x10x10 foot diving well using non conductive rope will that afford protection from all kinds of EMP? Would grounding a painted aluminum screen with fiberglass screen mesh enclosure suffice as a Faraday cage? By using a brass screen, you can make an enclosure in which you cannot send or receive calls, yet you can actually see into it or out of it. Depending on which urban legend is favored at the time, one might be led to believe the unusual building is some kind of nuclear facility or that it is home to the electronic musician Aphex Twin.
A local boy from Newington Butts, Faraday is most famous for his discovery of electromagnetic induction in 1831. Originally, Gordon had planned the structure in glass so that the transformer inside could be seen at work. To this day, many Londoners are confused by the memorial, and as recently as 1995 the London Evening Standard ran a story about the structure with the headline: "But what on Earth is it?" In 1996, however, the building received a different sort of publicity as a local schoolgirl won a BBC competition to devise a new lighting scheme for the site.
Foucault built a device that used a copper disk moving in a strong magnetic field to show that eddy currents (magnetic fields) are generated when a material moves within an applied magnetic field. Faraday discovered that when a magnetic field passes through a conductor (a material in which electrons move easily)-or when a conductor passes through a magnetic field-an electric current will flow through the conductor if there is a closed path through which the current can circulate.


However, it was not until the Second World War that these developments in the transmitting and receiving of electromagnetic waves were put to practical use for materials testing. In 1948, Forster founded his own company in Reutlingen, a business based on eddy current testing that continues to this day.
There have been many recent developments in eddy current testing, leading to improved performance and the development of new applications. I can remember thinking that the lightning was so close we were sure to be electrocuted any second and I was absolutely terrified.
It's basically used as a kind of buzz word, since people have heard of it, but probably don't know what it is. He found that by passing a magnet through a loop of wire, an electrical current flowed through the wire. Eddy current testing is now a widely used and well-understood inspection technique for flaw detection as well as for thickness and conductivity measurements. This work provided a basis on which Scotland's James Clerk Maxwell later developed the first comprehensive theory of electricity and magnetism. When, as it says in the article, in reality cars and microwaves and many other enclosures are faraday cages.
