I'll post some more images. I went for the diagonal first. https://imageshack.com/i/p9iQ6q4njhttps://imageshack.com/i/ipMPcPZ0j https://imageshack.com/i/exGgaxiUj https://imageshack.com/i/iqvEgAqSj

A Practical Squaring of the Circle. Does anyone know if this method of construction been done before? https://imageshack.com/i/exFv7X1Wj

No further questions. I found it interesting that when the hypotenuse of a right angle triangle is set to 1, it can be so useful when the sides as variable proportions are labeled differently.

I don't think this has been shown before. This is the closest example I could find. http://www.brooklyn.cuny.edu/bc/ahp/CellBio/RefIndex/RI.Main.html

Have some fun with this website. http://www.coolmagnetman.com/gallery/imageset.html

First I placed the magnets with opposite poles facing each other. I expected to see the ferromagnetic steel BB rapidly oscillate like a pendulum when suspended between the poles. This sort of happened, but wasn't good enough for a video clip. I then placed the magnets with like poles facing...

Don't know what to make of this. It is kinda like the stuff Felix Ehrenhaft wrote about. Is this why Tesla sometimes used a mechanical capacitor that could vibrate? Is it a kind of resonance between material and field? http://www.youtube.com/watch?v=DQBbCjcSORo&feature=channel

Hello marcusl; The surface of the water was not flat, so I could not do a real good experiment. Some day I might get a bigger container where the water might be more level in the center. The field lines also had too much curvature. I could rig up two cow magnets to get a 6 inch length instead...

Hello marcusl; I placed a cheap compass on the surface of water. The needle was pointing toward magnetic north. I moved a permanent magnet toward the container and the magnetic dipole of the compass needle felt torque and lined up in parallel with the magnetic lines of force, however the...

Thank you for your replies.

If there is a rule that ferromagnetic material be accelerated orthogonal to the magnetic lines of force, then wouldn't a spacecraft with ferromagnetic material onboard gain acceleration during a particular trajectory flyby above what is predicted by gravitation alone?

Hello Bob S; When the steel BB is pulled into regions of higher B, it is the path the BB took that caught my interest. If the geometry of the field lines is curved, then the path of the BB seems to be curved. A small magnet might not show it, but since the cow magnet is 3 inches long you can...
