Do permanent magnets fields change once outside of the earths magnetic poles and if so what occurs?

Question

I am interested in the values I.E. Do the magnets lose or gain strength ? Do the radiating fields change their configurations? Are any photos available which depict the fields while they are outside of the earths magnetic field? I am interested in any information which may be available including links to sites...Thanks in advance Larry

Answer 1

Any two magnetic fields will interact with each other. The same happens with the Earth's magnetic field and a magnet, although the Earths magnetic field density is very weak in comparison to a magnet.
The magnet will locally distort the Earths magnetic field, which can be seen by looking at a compass in just the Earth's magnetic field, then looking at the compass when a magnet is brought near.

Answer 2

Once they've swapped, not much, except for maybe some confused animal navigation and a lot of mislabelled compasses. It's the transition that's the problem. A swap doesn't just mean the North and South poles swing around to their opposite sides. The magnetic field actually inverts, collapsing in intensity down to zero, then regenerating as the opposite pole. During the "zero" part, Earth's electro-magnetic shield is gone and there's nothing to deflect the charged solar radiation. If it lasts for an hour or two, that's probably okay. But if the process takes a few years or more, we'd be in serious trouble. And since we don't know quite how it happens, we don't know how long it takes.

Answer 3

No, because they are permanent magnets.

Answer 4

Yes, they lose strength.

Answer 5

yes, less interference
