If the magnetic charge of the planet is declining, are there any idea about the effect to watch for in future?

Question

I believe the earth's magnetism is changing over time and might reverse completely. This could have big effects, beyond the need for an Ionic magnetic bracelet.

Could magnetic properties of the earth affect global warming somehow, or the ozone hole, or human health, vitality or height, etc?

Crazy ideas are sometimes true, much to our amazement. I think I'm talking myself into getting a magnetic bracelet. I've met people that swear by them.

Answer 1

The earths magnetic field is ever changing. The magnetic North moves 14 kilometres a year.

Scientists know that the magnetic field has flipped many times in the past and most believe the early stages of the next flip have begun. There are a number of magnetic anomaly areas where the flux flows in the wrong direction and these are expanding and moving.

No one knows whether the flip happens in years, tens, hundreds or indeed thousands or tens of thousands of years. But it does appear certain that it is going to happen again.

A flip in magnetic orientation would be unlikely to effect global warming unless it's strength changed which is highy unlikely.

The effects of magnetism on the body are less well known but there does appear to be some beneficial effects attributed to it.

Answer 2

One thing the field does is to attract charged particles, and shield the earth from this radiation. So if the field lessens, and/or changes, I think we will be bombarded with radiation, and you know what happens then. I read an article where the earth has shifted on it's axis a few degrees. This would cause more weather extremes.

Answer 3

There is evidence that the earths magnetic field has changed many times though history. The effects are unkown.

Answer 4

ok, i did not examine your total question yet via fact i became curious to work out if we agreed . . . observing beside the point issues is obviously volatile. We fill our hearts with pollution. i think of of ingesting nutrition as a metaphor. whilst that's real that an ice cream sundae on party is a robust ingredient, and not volatile, a slow nutrition plan of quite a few each and every night and potato chips and pa in the process the day will injury us as fairly as ingesting a pitcher of pungent spoiled milk finished of coliform micro organism. that's not mostly via flaws contemporary interior the chocolates and snacks, yet fairly via fact of what they don't comprise. we prefer solid, food-dense, total, sparkling non secular nutrition, and if we are consistently filling up on junk, there is no urge for nutrition nor any time for the solid stuff. you're what you "eat," you comprehend. . . . examine something of your question, and that i see you have not given a great style of your opinion, so yeah -- that's what i think of of television (and that i'm blessed to not have it with out issues handy -- yet then there is the internet :blush: )
