any body can explain why the circulation of the molten core inside a planet can produce magnetic field?

But we're not talking about local magnetic fields, are we ?DaveC426913 said:The core is constantly moving and charges are moving all the time. Electrons build up in places and are drawn from others. While the core as a whole may be electrically neutral, localized parts of it (even very large localized parts) will get charged.
hehe sorry but that was funny!DaveC426913 said:There are no molten larvae at the centre of the Earth. (Now THOSE would be some serious Killer Bees!) 'Lava' on the other hand... ;) *
That it was. As I was reading through the posts, I realized that the 'larva' thing needed to be pounced upon, but wasn't sure how to do it without making it sound like an insult. Well, done, Dave.Mariko said:hehe sorry but that was funny!

Please explain how this is possible.scott_alexsk said:From my knowledge it is not necessary to have plus or minus charges to have a magnetic field, more so the actual movement of the body creates the magnetic field.
scott_alexsk said:Just to let you know before you brutally cut me down, all I am trying to do is learn. In my view it seems that the magnetic field is caused by the slowing down of time around the particle and not so much the forces at work in the exchange of photons and movement of these. Does, theoretically, a nonmoving charged particle still have a magnetic field.

Start with a global communications blackout. There's also the possible extermination of most life. We live in a veritable maelstrom of energetic particles from both the sun and outer space. The magnetic field is our primary defense against them, hence the existence of the van Allen belt. Unless the 'flip' was very fast, our environment would be uninhabitable. We could survive underground, or in well-shielded buildings, but any exposed electronic equipment would likely be fried and electromagnetic communications would be impossible. Think of the worst solar flare you can imagine and up it a couple of orders of magnitude.quasi426 said:What might the consequences from this be?

Nor does anyone else on the planet !Danger said:As for what causes the reversal, and how it acts mechanically, I haven't a clue.
Scott, you do not have to justify your previous statements. We accept them as misinformed thoughts that we hope you will correct by asking asking questions, and learning science the correct way - the way that takes time, effort and dedication.scott_alexsk said:Although I currently believe my prior assumption was incorrect and that I am way over my head, the main reason I thought this made sense was because of the descripancy between objects speeding up and beginning to retain wavelike characteristics.
There is no physics in that last statement, so please stop, read and learn.The wave created by the expanded electron field of activity would act as the magnetic field.
As I understand it (and I am no expert, just a reader) the field tends to drop off dramatically, but it does not necessarily to reach zero. The axis of polarity merely wanders until it is reversed.quasi426 said:If the polarity is changing is there a time when the Earth has NO magnetic field since it must cross the zero point in order to swith polarity. What might the consequences from this be?
The planet's molten core creates magnetic fields due to the process of convection. As the molten iron and nickel in the core move, they generate electric currents, which in turn produce magnetic fields.
The molten core of a planet generates electric currents through the process of convection. As the molten iron and nickel rise and fall due to changes in temperature, they create a swirling motion that generates electrical currents.
The molten core plays a crucial role in creating a planet's magnetic field. The convective motion of the molten iron and nickel generates electric currents, which in turn produce the magnetic field that surrounds the planet.
No, not all planets with molten cores are capable of creating magnetic fields. The size and composition of the core, as well as the planet's rotation and speed of convection, all play a role in determining if a planet can generate a magnetic field.
Magnetic fields created by a planet's molten core have several effects on life. They protect the planet's atmosphere from solar wind and cosmic particles, which can be harmful to life. They also play a role in the navigation and migration of certain animals on Earth.
