Fossil magnetism also helped solved the problem of continental drift. Horizon: Message in the Rocks, BBC 1979
Dr Persinger has taken his research a stage further. He believes naturally occurring electromagnetic fields might also be capable of generating this sensed presence. This explains, he argued, not just our sense of God but perhaps also other supernatural experiences too. Horizon: God on the Brain, BBC 2003
So Horizon decided to set Dr Persinger’s theory and machine the ultimate test. To give a religious experience to one of the world’s most strident atheists Professor Richard Dawkins. ibid.
Despite the setback with Professor Dawkins, Dr Persinger’s research shone over a thousand human guinea-pigs has gone further than any other to establish a clear link between spiritual or religious experience and the temporal lobes of the human brain. It has put his research at the very cutting-edge of neuro-theology. ibid.
As the intense heat at the centre of our planet escaped it caused the liquid metal within the core to move. The ceaseless motion in the depths of the Earth is what creates the magnetic field we experience at the surface. Horizon: The Core, BBC 2011
And it’s the generation of this magnetic field that’s so vital to life on Earth. Because as charged particles are being blown off the sun the magnetosphere deflects them creating a safe haven for our planet. ibid.
If the magnetic field is continually changing, then that must be caused by how the metal moves in the outer core. ibid.
Our core may be a dynamo but it’s no simple one. Vast vortices and whirlpools create a magnetic field constantly in flux and that causes unexpected phenomena scientists are only now beginning to understand. ibid.
The Earth’s magnetic field could reach a tipping point and flip. ibid.
Something remarkable is happening in the heart of two of our biggest cities. One of the most advanced and expensive cancer treatments in the world is being installed in Manchester and London. This is no ordinary medical cure. It will involve two nine-ton machines firing beams of radiation at two-thirds the speed of light. It will cost more than a quarter of billion pounds, but it will save thousands of lives. Until now, patients in need of this pioneering treatment have had to travel abroad … Proton Beam Therapy. Horizon: The 250 Million Pound Cancer Cure, BBC 2019
A crucial piece of technology that will sit within it – the Cyclotron. ibid.
300 tons of magnets to focus the protons into a narrow beam. ibid.
Maxwell’s big idea was that magnetism and electricity are actually two facets of the same thing. Stephen Hawking’s Grand Design: The Key to the Cosmos, Discovery 2012
Light is an electromagnetic wave too. ibid.
At around a million billion degrees the electromagnetic and the weak force begin to merge. This merging is called electro-weak-unification. Through the Wormhole with Morgan Freeman: What Are We Really Made Of? Science 2010
Magnets generate invisible magnetic fields which flow between two poles. Professor Michio Kaku, Sci-Fi Science: Physics of the Impossible, Science 2009
Even the atom is a dipole. ibid.
We can summarize electricity, magnetism and gravity into equations one inch long, and that’s the power of field theory. And so I said to myself: I will create a field theory of strings. And when I did it one day, it was incredible, realizing that on a sheet of paper I can write down an equation which summarized almost all physical knowledge. Michio Kaku
Electromagnetism not only explained the relationship between electricity and magnetism, it would go to explain the very nature of light. Of radio waves. Of X-rays. Michael Mosley, The Story of Science: Power, Proof & Passion, BBC 2010
In the winter of 1943 Nikola Tesla looked out across the Manhattan skyline for the very last time ... He saw a new world, a world transformed, a world powered by electricity, his world. Jim Al-Khalili, Shock and Awe: The Story of Electricity 2/3: The Age of Invention, BBC 2011
Harnessing the link between magnetism and electricity would completely transform the world. ibid.
[Michael] Faraday had proved that this invisible force really does exist and he could see its effect – circular motion. ibid.
Faraday had generated a continuous flow of electric current. ibid.
The key to understanding the telegraph is understanding a special kind of magnet – an electro-magnet. ibid.
The 1858 cable was never fully repaired. ibid.
A new branch of research into the electromagnetic spectrum, and solve the problems of the Atlantic telegraph. ibid.
A new way of using electricity – to make something every person in the world would want – electric light. ibid.
[Thomas] Edison had assembled a group of young and talented engineers. ibid.
The race to bring electric light to the world was to play out in the great cities of the time. ibid.
America’s first power station generating continuous direct current. ibid.
Tesla was less impressed. He had a dream electricity could be transmitted across entire cities or even nations. ibid.
Westinghouse believed alternating current was the future. ibid.
Tesla was paid $75,000 for his alternating current patents. ibid.
Westinghouse and Tesla went toe to toe with Edison for New York’s lucrative lighting contracts. ibid.
Edison claimed that AC was a more dangerous type of current than DC. ibid.
In an almost magical display of awesome power and wonder and without wearing any safety chainmail or mast tens of thousands of volts produced by a Tesla coil passed across his body and through the end of a lamp he was holding. ibid.
James Clerk Maxwell would become one of the leading lights of nineteenth century Physics. His work on electricity and magnetism was one of the great achievements of the age. Jim Al-Khalili, Light and Dark, BBC 2013
This is the wave equation ... the speed the wave is travelling. ibid.
300,000 kilometres per second: the speed of light ... an electromagnetic wave. ibid.
One of the biggest dangers out there – Magnetic Electric Fields ... Didn’t we do a show just last series about people who want you to wear magnetic fields to help you heal? Penn & Teller, Bullshit! s2e2: Safety Hysteria, Showtime 2004
This bizarre story began in 2008. Zoologist Hynek Burda was analysing satellite imagery of the Earth’s pastures. What he found was remarkable – across the world ... hundreds of millions of cows were facing in the same direction – either north or south. Weird or What? Ghost Ship, Discovery 2010
Until recently we believed that the space between the stars and planets was empty – a vacuum. We now know it is teeming with charged particles. We see glowing electric filaments spanning millions of light years. PSTV.tv – Thunderbolts of the Gods, Wallace Thornhill
It is possible the predominant force in the universe is not gravity but something else ... A new theory is being proposed ... It is in fact a synthesis of the disciplines ... The Electric Model offers us a new interpretation of the workings of the universe. ibid.
The Electric universe on the other hand deals with the electric structure of matter at the atomic level and works its way up. ibid.
Magnetic fields are threaded through space in all dimensions. ibid.
Electric current, after passing into the earth travels to the diametrically opposite region of the same and rebounding from there, returns to its point of departure with virtually undiminished force. The outgoing and returning currents clash and form nodes and loops similar to those observable on a vibrating cord. To traverse the entire distance of about twenty-five thousand miles, equal to the circumference of the globe, the current requires a certain time interval, which I have approximately ascertained. In yielding this knowledge, nature has revealed one of its most precious secrets, of inestimable consequence to man. So astounding are the facts in this connection, that it would seem as though the Creator, himself, had electrically designed this planet just for the purpose of enabling us to achieve wonders which, before my discovery, could not have been conceived by the wildest imagination. Nikola Tesla
Over the past thirty years Louise J Greenfarb of Las Vegas, Navada, has collected more than 29,000 fridge magnets. Ripley’s Believe It Or Not?
