The Earth's magnetic field deflects solar winds which contain charged particles. These particles would be fatal to human beings.
Yes we do!
Almost all creatures sense magnetic field except us, human.
If it is a constant magnetic field, probably not (if you die, let me know). Often, however, we have to tolerate varying magnetic fields. I am not sure, but I think that puts more stress on the human. For example, a varying magnetic field will induce electric currents.
I am not sure what you mean by widening. The Earth's magnetic field is a result of the fact that the Earth has a molten Iron core and the planet is rotating quite rapidly. The strength of the magnetic field in these circumstances is dependent on the speed of rotation. As the Earths rotational speed is slowing (due to the friction of the tides caused by the moon) the Earth's magnetic field is gradually weakening over geological time scales but this is not significant in terms of human time. The other affect of the rotating Iron core on the magnetic field is what is called field inversions. In the same was as the Sun goes through an 11 cycle of activity during which the N and S magnetic poles flip, the Earth's poles also flip about once every 75-100 thousand years. There is some evidence that the Earth's poles are in the process of flipping at the moment and during this process, in the same was that the Sun develops Sun spots, multiple poles appear at various locations round the Earth. This effect could be said to distort (or widen) the Earths magnetic field.

Yes, the human body produces a magnetic field due to the electrical currents generated by the nervous system and the heart. This magnetic field is very weak and not strong enough to be considered significant compared to other magnetic fields in nature.
The human magnetic field is very weak, about 100 times weaker than the Earth's magnetic field. Factors that influence its intensity include the body's electrical activity, blood flow, and the presence of metal objects.

Earth's magnetic field acts as a shield, protecting us from harmful solar radiation and cosmic rays. It also plays a crucial role in animal navigation and migration, including some species of birds and sea turtles.
the chemical composition of human beings are similar to that found in the reminisce of stars after they impload this answer is correct human beings cant be chemically composed like earths crust because we arent formed from silicates and crystals
