That's news to me... last thing I heard, is that they're theoretical entities but have never been detected. In fact, a significant number of scientists doubt they're actually real.Monopoles have only recently been shown to exist in nature though they were theoretically possible before
On the other hand, "natural" monopolies only exist because of the extra rules governing them (more precisely: governing their competitors)...Monopoles have only recently been shown to exist in nature though they were theoretically possible before, with lots of extra rules governing them.
Keeping on topic of north vs south, when the Earth's magnetic poles flip orientation, things will become weird.Let's get this straight.
1) North and South are arbitrary names.
2) The North geographic pole is accepted as the one nearest to the Arctic Circle.
3) The end of the compass that points to geographic North is declared to be a north magnetic pole, i.e. it is the geographic North seeking pole.
4) Therefore the Earth's south magnetic pole is located in the vicinity of the Earth's geographic North.
Charge and current have handedness. This affects, the direction of the magnetic dipole.
DC parallel, but separate, a left handed wound coil and a right handed wound coil.
Core them with iron.
The left hand coil will produce a S magnetic pole, in the direction of actual(electron) current.
The right handed coil will produce a N magnetic pole in the direction of actual(electron) current.
The flux opens at the N pole and closes at the S. If you bend and close the coil, most of the flux will remain in the closed dipole state, within the coil, expressing neither a N or a S pole. Just an internal pole-less direction. A uni-pole.
So, a battery and a coil of wire, a nail.......can predict and detect the Polarity of a known and therefore an un-known magnetic pole.
Then the exercise is pointless.But what if you dont break it?
One of the sites stated that it occurs periodically and the geologic evidence points at 2000 years ago??? What evidence??? I thought it was armageddon when it flipped??? It's all too confusing as it is now. Especially with joey throwing monopolies into the discussion LOL.Keeping on topic of north vs south, when the Earth's magnetic poles flip orientation, things will become weird.
Isnt it measured in rocks and/or ocean cores?One of the sites stated that it occurs periodically and the geologic evidence points at 2000 years ago??? What evidence???

Gosh... you've just created a brand new branch of physics: "The Economics of Magnetism"Especially with joey throwing monopolies into the discussion LOL.
What is "it"??? I have no idea what they are referring to? If I remember correctly the root cause of Earth's magnetic field is our liquid iron core and it's sloshing around can cause the poles to swap? Then what happens other than compass direction suddenly changes? Every time the US Geological Survey printed a new map about every 10 - 20 years on it's compass rose it would notate the deflection between True mapped North and magnetic North and good compasses are adjustable to compensate for the local deviation. Which is constantly changing albeit not by very much. The actual deviation can be a few degrees or not hardly any if at all.Isnt it measured in rocks and/or ocean cores?
No i was talking very long term measurements where certain natural materials indicate large pole shifts much unlike those of today.What is "it"??? I have no idea what they are referring to?

That's just it, what natural materials. I took some geology and paleontology in college and the paleontology indicates times of drastic changes in flora and fauna, but what indicates magnetic changes?long term measurements where certain natural materials indicate
Didnt i mention that?That's just it, what natural materials. I took some geology and paleontology in college and the paleontology indicates times of drastic changes in flora and fauna, but what indicates magnetic changes?
Hello,My geology was 40+ years ago. Curious as to just what it is they see that says "hey the Poles swapped". My understanding was that it would be a near-extinction catastrophic event. Of which there have been several in the paleologic records usually attributed to water or ash evidence.
