Ok hypothetically speaking if the Earths magnetic field increased what effect would it have on humans?

Answer 1

A stronger magnetic field would repel more, heavier and faster "charged" particles. You've heard of them as "cosmic rays".

This stronger field would block more "radiation", yes, but only electrically charged particles. It would not increase gravity and it would not reduce the UV that will give you a sunburn.

It is possible, though, that a stronger magnetic field would slow down evolution of all species of life on Earth. The little mutations that, over time, allow species to find novel adaptions to changing environments may be less numerous. In some cases, that loss of mutation over the generations, may doom some species that have difficulty adapting anyway. When those heavy, fast and charged particles hit particular DNA base pairs in particular cells - a mutation can result.

Other than that, which I think might be the most important effect, there might be another (less important) effect. This one would concern the aurora borealis and australis, the northern and southern lights. If the magnetic field were to become exceedingly strong, one could imagine more brilliant displays as a result of capturing more particles, funneling them down with greater flux density and plowing them through our upper atmosphere causing it to be ionizing more brightly!

Answer 2

Most planets have no significant magnetic field that you can interact with, the magnetic field of the sun also dominates them all. Also the poles of all planets are pointing in pretty much the same direction, towards the solar zenit/nadir. you could only make planets changes their orbit planes, but not change the shape of the orbits by small accelerations. Planets are kept in orbit by the gravity of the sun, even by making Earths magnetic field 1000 times stronger, you wouldn't even change anything for the other planets with magnetic field. Jupiter for example has a very strong magnetic field, but would rather pull Earth out of its orbit than the other way around. Gravity is not magnetism. Gravity has no poles and gravity can't be neutralized. All electricity by solar power wouldn't be enough for making Earths magnetic field twice as strong: Earth is a huge planet with a strong magnetic field. The weak force you experience by it does not change the fact that the same magnetic field reaches way past the moon on the side away from the sun, and is about one million times stronger than the magnetic fields of Mercury, Mars and Venus. Also, if you could really manipulate Earths magnetic field, you would not want to be so stupid to try to attract other planets, you would turn Earths magnetic field into a propulsion system and use the magnetic field of the sun for pulling Earth slowly through the solar system. Sadly, this means you would need first to tilt the rotation axis into the orbit plane of Earth... you essentially need to destroy Earth.

Answer 3

Studies have been made on the effect of magnetic field on Humans.A critical one was the effect that MRI equipment which can produce a magnetic field of a few Tesla,has on the MRI technicians.
No detrimental effect have been observed.
Animals such as birds are said that their brains responds to magnetic field ,hence they would navigate on a magnetic radial signal.
Perhaps an increase in magnetic field on the VanAllen belt would derease the detrimental radiation from the solar wind.
Hence a change radiation wouldi indicate a Change in Human life span.

Answer 4

More radiation would be blocked from reaching the Earths surface.

Answer 5

gravity would stronger thus pulling us closer to the ground and making us maybe shorter and fatter.

Answer 6

Harder to get a sunburn.

Answer 7

less sunburns, yessss!!!
