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 magnets of equal size and strength.
One magnet has a convex glass lens adhered to each pole end.
One has no lenses.
Each magnet is suspended above a wood table (no metal anywhere near) using plastic shims.
A white card stock paper is laid over each magnet
Fine iron filings are sprinkled (as evenly as possible) from a shaker over the paper
The magnet with the lenses exhibits sharp deformation of fields, creating a well defined pattern significantly different from the norm, bending the field upward and to the sides of the lens and essentially removing the fields from the usual outward direction.
The magnet without the lenses, exhibits the familiar pattern usually associated with a bar magnet.
Remove the lenses from one magnet and apply to the other, and the same patterns are observed for the newly lensed magnet.
The effect extends greatly into the bar itself, up to a third of its length using the lenses I have. The effect changes when the lenses are changed and using a different magnitude lens.
I will be trying a concave shaped lens later, but wanted to post this for possible input on this result.
This experiment idea comes from the fact that light is rotated and bends when passing through a magnetized glass plate (Faraday effect and other variations) but it seemed to me that if light bends through a lens, then magnetic fields should also be affected by the structure of the glass. However, I find no reference to this effect using the normal terms in Google or other search strings.
Please respond with suggestions and or explanations.
.. Since posting I have subsequently tried a variety of magnet combinations, and have successfully "killed" the magnetic field around a small horseshoe magnet. In other words, no filings will stick to the magnet at all in any spot on the magnet. By placing the lens in between the two poles the effect is the near extinction of the magnetic field. Remove the lens, and the field returns to normal.
Any thoughts on this phenomenon will be greatly appreciated, as this seems unusual. It seems to me that someone at some time must have tried this out before, although who else would think to stick an optical lens on the end of a magnet.
