Sword in the Stone story where the sword was held in place by electromagnets












15















So some years ago I read a story that included a "sword in the stone" bit and it was explained that the sword was held in place by electromagnets that could be released when "the one" tried to pull the sword out.



I don't remember how integral to the story this bit was (it might have been just an aside about how the current king had been picked). I also don't remember if this was part of a full novel or just a short story. I think time travel was involved as the setting was "fantasy-esque" and the whole electricity/magnet connection was obviously an anachronism.

  • It also appears in the Scorpion series (one episode occurs in a medieval festival and someone acts as Arthur releasing the sword but a genius notices and reveals that there's an electromagnet maintaining it)

  • Another side note: the trick (or one very much like it) works well. I was the adult from the audience of a magic show who couldn't lift a box a child could. It was held down with a large electromagnet in a stand that was weighted down with my own weight, and had a steel plate in the bottom. I'm a scientist/engineer so I spotted it despite the well-disguised switch - but of course I didn't let on.

This may be "Once and Future" by the late Terry Pratchett, first published in Camelot in 1995. A time-travelling historian named "Mervin" gets stranded in an anachronism stew that mostly matches Arthurian legend, and he reproduces the sword-in-a-stone bit in order to get a king who will follow his advice for advancing technology.




All the mechanical ways of doing it I had to rule out. That left electricity. Strange thing is, it's a lot easier to make a crude electrical generator than a crude steam engine. The only really critical things are the bearings.



And the copper wire.




And then, when the sword is pulled, Mervin finds out how this Albion is different from ours:




Uther had a daughter in this world.

It's been a long time since I read them, but I believe Merlin used a lodestone (magnet, but not electromagnet) in this way in A. A. Attanasio's The Dragon and the Unicorn series. Sadly I can't find a ready summary now.
