hello
ive never studied physics or any science in any depth, but am fasinated by the phenomenom of magnetism
ive recentley being doing research into magnetism, because i couldnt understand why forms of levitation through through magnets arent more widely seen, even though we are living on a huge magnet. which begs the question, if two small magnets repel each other, why cant the earth repel a magnet opposite to itself?
i presume this has a simple answer, but would be grateful if someone could tell me what it was!
thankyou. |

The earth is not really a magnet. Friction from the atmosphere spinning with the earth and the edge of space where the atmosphere meets space, creates a field.
The earth accelerates ambient radiation. So that there is not as much repulsion from the solar charged space, near the earth. The slowed excited area creates gravity/repulsion. The earth accelerates not blocks the ambient radiation and there is almost no repulsion from the earth. So the natural repulsion pushes you to the earth, that has less repulsion.
Sincerely,
William McCormick

Actually, they did research and found that molten metal spinning on an axis creates a magnetic field; they did this experiment with mercury and created a field, albeit much smaller, similar to the earths.
The magnetic field is not powerful...it only stops cosmic rays because of its sheer size, not density. This is why a magnetized needle cannot turn on a wood or metal surface, there is so little force being applied that static friction prevents motion, so you put it on the surface of water where the friction is mush less so that it can align with the earth's field.
The problem with using the earth's field combined with one of our own to levitate is that we would need an electromagnet (not a normal one due to weight) of unbelievable power and low weight. Even those that CERN uses are not low weight and powerful enough the accomplish levitation with earth's low density field (even though they are made of titanium niobium). We would have to entirely reinvent our methods of generating a magnetic field...and even then it would be difficult to utilize. Take a large cylindrical magnet on a surface and point a smaller one at it in various different places. The forces you feel on your hand are similar to those that the craft would feel, making it tremendously difficult to maintain balance and the correct polarity while traveling long distances.
Overall it would not be a good idea to seek such a method of levitation; even our ancient Newtonian methods of propulsion are much more practical and economically reliable than this.

Did they try just spinning the glass container without the mercury or molten metal?
Anything spinning in air will create a magnetic or electrical field.
Did they spin mercury in a vacuum. And check the difference between mercury spinning in a vacuum and mercury spinning in an atmosphere of air?
In a vacuum the mercury will create a vapor so the experiment might not be valid anyway.
Sincerely,
William McCormick

It was completely contained in some sort of Plexiglas sphere, with no air inside. I do not know what kind of controls they used.

There are a couple problems with spinning things on a different scale. And saying that you are getting magnetism.
Think about the earth. If as, I am ever saying that ambient radiation is racing through the planet at speeds faster then light. The angular change the earth will create to the path of ambient radiation will be small. Even at 1500 feet a second at the Equator.
However if you turn a small object to 1500 feet a second at its surface, you are doing something very different. You are altering the angle of the object much more quickly. So that ambient radiation has to alter its course much more. Creating magnetism and even gravity like effects.
Take that small object and spin it once in 24 hours and you are going to be magnetism light.
I am not being a stickler. Or a fool or troll. I just do not like how points are made without looking at the whole experiment. Nothing wrong with what you did. I thank you very much for bringing this experiment to my attention. I would like to know more about it.
Spinning plastics quickly can create the same effects.
Sincerely,
William McCormick
