Discussion Overview

The discussion revolves around the numerical breakdown and variations of Earth's magnetic fields, including a historical reference to an experiment by Nikola Tesla. Participants explore the feasibility of replicating such an experiment and seek specific numerical data regarding Earth's magnetic fields and the requirements for constructing a magnet for this purpose.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant recounts an experiment by Nikola Tesla involving magnetizing a sphere to replicate Earth's magnetic field, questioning the necessary electrical charge for such an experiment.
  • Another participant expresses skepticism about the validity of the Tesla experiment, requesting references to support the claims made.
  • A later reply mentions a biography of Tesla by Margaret Cheney as a potential source for verification of the experiment.
  • One participant emphasizes the need for numerical representations of Earth's magnetic wavelengths, noting that these may vary by location and suggesting that a mean value could be determined.

Areas of Agreement / Disagreement

Participants do not appear to agree on the validity of the Tesla experiment, with some expressing doubt and others seeking to verify the claims. The discussion remains unresolved regarding the specifics of Earth's magnetic fields and the feasibility of the proposed experiment.

Contextual Notes

The discussion includes references to historical texts and personal recollections, which may lack precise citations or verification. The numerical values and methodologies for measuring Earth's magnetic fields are not established within the conversation.

through lots of research I came across a little experiment conducted by Nikola Tesla. This Experiment consisted of magnetizing a sphere to the same the Earth produced in the given area where the experiment was to take place. Taking the spin of the Earth approximate wind effects on the sphere a location was determined and the area was informed of falling objects. Once the Sphere was charged it shot into the air, apparently with great force and speed, never to be seen again.

with that said, I would like to know the numerical break down of Earths magnetic fields and variances that would have and would allow an experiment like that to take place. This would include the construction of the the magnet. How much electricity would be needed to charge a given material to permit the to be repeated?

Hi Randomize! Welcome to PF! :smile:

:confused: Sorry, but so far as I know this is rubbish …

Tesla did no such thing …

can you please provide a reference and a link for this? :redface:
 
I was young at the time so my note taking is not what is today. But it was a biography written about Tesla by a female author. it was worn by the time I got to the book but I did mange to get all the reference used to write the book. I will look over my notes and see if I did write down the book and ISBN and give that information. If not I will do the research to find the book and then post the information for verification.
 
Okay I found the book, it is "Tesla: Man out of Time" written by Margaret Cheney. The page number is unknown to me. I no longer have the book to get it for you. This should help to support my statement even slightly.
 
While I wait for the book the main point of this post before it's forgotten is acquiring the magnetic wave length(s) and numerical representation of those wave length(s) for the planet. Being that the wave length(s) vary depending on where one is on the planet then a mean number should be able to be acquired. This is what I am looking for.
