Earths magnetic feild ...

The core of The Earth is made from flowing molten iron, teamed with movement - produces a magnetic field around The Earth.

From what I can find, the South Pole is 'positive' and the North Pole is 'negative'

As each 'planet' has some version of this (including the sun) - (who switches poles every 11 years, also has 'solar flare' where us on earth get more charge and big events seem to happen?)

My question is does that conquer that the southern hemisphere has more 'positive' ions and the opposite for the North? and does this effects us in someway?

If anyone can point me to some more reading that is easily digestible that would be great. Or drop some knowledge.

The terms 'Positive' and 'Negative' are arbitrary. For example people originally thought electricity was made of positive particles, and so even today we treat electronic circuits as if they are positive while in reality they are formed by electrons moving in the opposite direction of the current that we imagine. For example if you put a battery into something to power it, you imagine that positrons are leaving the + part of the battery and traveling towards the - part. In reality there are electrons which leave the - side of the battery and travel towards the + side, and there are no positrons moving at all. The motion of electrons is in the opposite direction of that imagined, but for purposes of analysis there is no difference. You get the same result whether you presume positive particles are moving towards the right or negative particles are moving to the left. Therefore the terms 'Positive' and 'Negative' are arbitrary. What matters is that there are two opposite charges for ions and cations.

Earth's magnetic field does not reverse very often like the Sun's does. When it does reverse, it makes a magnetic mark in rock strata. Geologists have developed techniques which allow them to see changes in polarity in some rocks.

Some animals are sensitive to Earth's magnetic field. It is now known that some migratory animals use Earth's magnetic field for part of their navigation. If the field were to reverse it might affect their migration for a while. Nobody knows what they will do to adjust, but apparently they have gone through such changes before. It will be interesting to see.

When the Sun has a solar flare, it means that more particles flow from the Sun out into space. Many of them strike Earth's magnetic field, which bends their paths towards our Northern magnetic pole, creating the Northern Lights effect. If the polarity should reverse then the 'Northern Lights' will move to the Southern magnetic pole and compasses will point South instead of North. Other than that things will probably not change very much, or at least I hope not.

Just a small note of correction.
"Northern Lights" also exist at the south pole. They're called the Southern Lights: Aurora Australis. In turn, the Northern Lights are termed Aurora borealis.

May you excuse me to explain this a little further. As per the battery example are you saying that there is an origin of charge from the North pole?

There's not any charge that you would feel, however if you travel East to West or West to East there is a small current induced in your body as you move across the Earth's magnetic field (not talking about gravity just the magnetic field). That is probably how the animals detect the field. For all practical purposes the field is not doing much to you, however as a conductor moves through the field a slight current must be induced. This is relatively small, probably not significant; however you may be able to detect it in your body.

There are charged particles that result from the solar wind, but this amounts to some chemical energy that is mostly released as light. The air absorbs the brunt of the solar wind. The charge is (probably) much less than is already generated by our own atmospheric conditions such as thunder storms.

The magnetic poles do not coincide with the geographic poles. They wander around, and right now the north magnetic pole is traveling at about 25mph toward Russia and is at about the position shown on the map.

Even if i may not be able to feel it, this seams like something that could possibly be harvested for free energy? (or/ be a dope portal)

There are also indications now that we seeing the start of another flip Earth's Magnetic Field Flip Could Happen Sooner Than Expected

Yep, i am feeling it. Maybe this is also a factor in 'global warming' stats.

There is a charge difference between the ground and air, but its mostly due to sunlight. Collecting the charge potential as an energy resource is possible, but there is an amount of charge not an unlimited amount. It has uses in nature (lightning) and helps to make ozone. Its just a question of how to collect the charge and how to do it responsibly. We can already collect sun energy using solar panels, wind turbines and hydroelectric turbines. These are established tech that work well.

Electricity collected from the air could become the newest alternative energy source - American Chemical Society
