Does the island of Magnesia in Greece still have those magnetic deposits?

Question

I thought that being known since 800 BC mustn't have been something in favour of their existence but still, are they still there?

If they are or would have been there, how would have they affected the daily life there?

Do they or did they fascinate the researchers and physicists?

Really a very broad question but yea.... I am curious.

Answer 1

You bet it does!
These were the originally recorded source of the lodestone or ferric ferrite ((Fe)3(O)4) actual dates back to seventh century BC not ninth. As you know this is because to the island’s name the term ‘magnet’ came from. Or see reference #1 for a different story Hmmm ... interesting?
What is fascinating is the work of Dr. William Gilbert who in 1600 published his work "De Magnete" based on experimental findings. What is that he noticed that a needle ones magnetized and suspended in a liquid will orient it self north to south and also will tilt a bit downward. Does it point to the iron core of the Earth?

Otherwise the lodestone and its ‘original’ place caries little scientific mystery.

PS and actually Magnesia is not an island (see ref #3)

Answer 2

I guess that I won't be taking my laptop there on my next trip :-)

I don't have the definitive answer, but in relation I watched a program a while ago that mentioned that the actual Arc of the Covenant, possesing the supposed power to strike down any person that opens it potentially had utilized magnetic fields to protect it.

By one theory, the large box as it was could have been constructed in a way that it would act as a giant capacitor. This capacitor, if hidden or stored in a location that had an irregular magnetic field about it would be charged over time by this magnetic inference, therefore containing enough energy after a period of time to deliver a lethal dose of high voltage when opened.
