So the apparent pattern of lines are nothing more than an illusion! Your examples make this clear.
I believe you've answered my question. Thanks for your assistance.
The arrangement of the spikes in the video looks very regular - I'd think that if this was due to small displacements of the surface, then the position and/or height of the spikes would be more variable. On the other hand, I can see the possibility that the attraction of more ferromagnetic...
Yet when iron filings are put on paper and a bar magnet put underneath, the iron filings coalesce along these lines - presumably that's why pictures of magnetic fields in books are shown this way!
This video shows the effect a magnet has upon a "magnetic fluid" - the result is a series of...
Unfortunately this is not what I'm looking for - although the first video did provide an explanation for an apparent contradiction: explaining a magnetic field using relativity when the election are not moving at relativistic speeds. This explanation does raise further questions - would the...
Both the gravitational and electric fields associated with matter are centered on the matter itself.
However, for a bar magnet, the magnetic field seems to be emanate from discrete loops, only part of which pass through the matter of the magnet.
What causes a magnetic field to have this...
I've been studying physics for some time just for my own curiosity.
I've been visiting for several years to read the various forums and Insight articles, and have finally joined
because I'd also like to ask questions, and hopefully get answers.
