Magnet Myths and Misconceptions

[MarkE]

Its well known today in ALL PHYSICS that Your claim is Wrong MarkE - A Long Solenoid proves, and blows your prehistoric textbook theory, with NO experimental evidence to prove other wise! Right out of the Water!

You have nothing to stand on!

This is beyond face palm material.  Anyone with a hobby store or Radio Shack nearby can purchase the materials needed to perform the grade school experiments that have been conducted countless times.  Those experiments support the correct conventional view that the magnetic lines of force go from pole to pole and not from either pole to the dipole mid-point as shown in my prior graphic.  Feel free to repeat such an experiment and show whether you get the result that "prehistoric textbook theory" predicts or the compass deflects perpendicular to the dipole at the center as your claims require.

The field changes polarity pole to pole. The transistion zone is neutral. This is what the video shows

MarkE - Your experiment proves nothing other than a Compass Works! That the North Pole of a Compass is Attracted to the South Pole of a Magnet and vice versa!

It proves nothing else! It DOES NOT prove that the Lines of Force you propose from Pole to Pole are Contiguous or even exist! This is a TOTALLY PROPOUSTEROUS Argument! So you're essentially saying that the Earth HAS NO EQUATOR?

You're Impossibly Confused with High School Science from back in 1932 I think!

Oh but they knew then that there was an Equator, or were you off sick that day? Cant have been because your previous drawing clearly shows a boundary between North (Red) and South (Blue)!

[tinman]

Tinman as is taught in school and has been known for many, many years, the field around a dipole follows a contiguous closed path from pole to pole.  You can see this for yourself with a very simple experiment.  All you need is a compass and some bar magnets that you can configure into a dipole much longer than the compass diameter.  Align the dipole along east west.  Position the compass at points around the dipole from one end to the other and note the needle position.  The needle aligns with the field.  The north seeking end of the compass needle will point along the field lines away from the north magnet pole parallel to the lines themselves.  If as is proposed the lines turned inward towards the magnet at the dipole midpoint, this would be immediately obvious.  They don't.  As in the conventional view, the compass indication is most stable near the dipole midpoint.

As i said,your analogy is incorrect,and cannot be shown with a compass. See my modified picture below. As you can clearly see,the compass will still show exactly the same as it would in your example.The magnetic polarity of the compass needle is simply being attracted to the opposite poles of the magnet. To say that the compass needle should point toward the center of the magnet if my analogy was correct is also wrong. To what pole would the north attracting end of the needle on the compass point to,as the center of the magnet has both a north field and a south field. The field at the center of a magnet(between each pole end)is concentrated within the magnetic material it self,and only at the pole ends dose that field extend beyound the magnetic material. The field then tappers from the pole ends back into the magnetic material near the center between the two pole end's.

Tinman, your model fits much better in the overall spectrum of data than the crazy Iron Filing Model! - There is an Equator, also known as the Bloch Wall! Its there, its undeniable to anyone that has a partial clue on Magnetics!
