Agreed, that the standard definition of a "Field" when describing EM is a reference to points in space, rather than something physical, like a corn field.
However, folks tend to think of a magnetic field as a physical thing, since it produces physical effects. And what if the magnetic "field"...
Pallidin, that is a fair question. Why has this question not been definitively answered in the last 200+ years? I have spent more time trying to find reputable answers to this than I have spent actually working on experiment. Most of the proposed experiments are too overcomplicated or are...
I have a moving magnetic field that rotates around the polar (Y) axis - see below - and I want to translate the energy in the form of electricity, what should I try.
1) I have created a magnetic field that rotates around the polar axis from the surface of a disc shaped magnet to about 1.5"...
Yes I see, but what I'm trying to understand is this... In the example, the train uses a solid conducting disc attached to the wheels. how would you capture the electricity from a disc like this. I can understand using a series of coils arranged in a circular fashion around the wheel, with a...
I have read that locomotives use eddy current braking systems, and one article mentioned that this system has also been used to charge batteries in a recovery circuit. However, I can not find details on this idea. From what I understand, the train has conducting discs attached to the wheels, and...
Besides expanding and collapsing a magnetic field through a conductor, does anyone know of a method of producing electric current when the conductor and magnetic field are stationary relative to one another? I am familiar with the Homopolar generator (faraday disc generator) as well as all the...
I am not sure if this is an appropriate area for this topic, so please re-direct if necessary.
As I understand it, according to Coulomb's Law, Electrons should repel each other (except under certain circumstances such as super cooled as in a superconductor) However, I am having a hard time...
After many many experiment with different lenses of different substances, I can report the following.
1) out of all the lenses I've tried, the original lenses as posted were the only ones that caused this slight deflection of the pattern of iron fillings. All others were, as far as I could see...
yes, the pattern by themselves, still look similar to other by themselves, but when compared side by side, there is a definite difference as you can see in the image. I've tried to be as careful as possible to ensure that the top of the lens is not supporting the paper, even setting the lens...
I know, it is a bit strange, but here it is. This could be a possible diamagnetic effect, but with two slightly different focal lengths of lenses, I get two slightly different patterns. The small horseshoe magnet is very weak, and that probably has something to do with what happened with it, and...
Hello all,
doing some reasoning and subsequent Gadenkin experiments, followed by a Non-scientific experiment results in some interesting changes in magnetic fields using glass lenses. Here it is, and please help me to explain this phenomenon, as I can find no mention of it anywhere.
Two bar...
I know this may sound strange. Has anyone ever successfully created a working physical model of a magnet that exhibits the same properties ("flux" lines and attraction) without using magnetic materials or electrical influence?
Thanks
