Putting stuff orbiting around the Earth would be harder (parasite Eddy current would have much stronger effect) At same time astronauts around Earth would receive much less radiations from space. Certain metals would be heavier due to attraction caused by magnetism.Jun 5, 2015
Why is it important that Earth’s magnetic field remain strong?
Earth's magnetic field is thought to play an important role in making the planet habitable. Not only does a magnetic field set the direction of our compass needles, it also acts as a shield of sorts, deflecting away solar wind that might otherwise eat away at the atmosphere.
What would happen if the Earth’s magnetic field changed?
If Earth's magnetic field were to decay significantly, it could collapse altogether and flip polarity – changing magnetic north to south and vice versa. The consequences of this process could be dire for our planet. Most worryingly, we may be headed right for this scenario.
What would happen if the Earth has a weak magnetic field?
A weaker magnetic field will make the planet more susceptible to solar radiation and put space equipment at risk.
What does Earth’s magnetic field affect the most?
Earth's magnetic field deflects most of the solar wind, whose charged particles would otherwise strip away the ozone layer that protects the Earth from harmful ultraviolet radiation.
Can the earth lose its magnetic field?
If Earth lost its magnetic field, there would be no magnetosphere – and no line of defense, even from weaker solar storms. Our power grids would be more vulnerable than ever, and even our computers and other electronics could suffer damage if a solar storm struck.
Will the Earth’s magnetic field remain forever?
Presently, Earth's magnetic field is weakening in strength by 5% every 100 years. It may be near zero in another few thousand years at this rate!
What will happen if the magnetic pole flips?
During a pole reversal, the magnetic field weakens, but it doesn't completely disappear. The magnetosphere, together with Earth's atmosphere, continue protecting Earth from cosmic rays and charged solar particles, though there may be a small amount of particulate radiation that makes it down to Earth's surface.
Will Earth ever lose its magnetic field?
The first thing to understand about the magnetic field is that, even if it weakens, it's not going to disappear — at least, not for billions of years. Earth owes its magnetic field to its molten outer core, which is made mostly of iron and nickel.
What would Earth be like without a magnetic field?
But what would happen if Earth's magnetic field disappeared tomorrow? A larger number of charged solar particles would bombard the planet, putting power grids and satellites on the fritz and increasing human exposure to higher levels of cancer-causing ultraviolet radiation.
