Earth's magnetic field deviates high energy particles (e.g cosmic rays) that are a risk for human health.

Explanation:

Cosmic rays are high energy charged particles (88% protons, 10% nuclei of helium, 1% heavier nuclei) that came from the outer space. The energies of these particles are in the range of 1 GeV to 10⁸ TeV. Since they are charged particles, they will be deviated by Earth’s magnetic field¹ (as a reminder: A magnetic field applies a magnetic force over a moving charged particle).

Earth’s magnetic field works as a shield to humans against high energy charged particles, if cosmic rays were in touch with a human body, it can break molecules that forms DNA structure². Modifying that structure can lead to diseases as cancer, for example.

Units:

GeV: Giga-electronvolt

TeV: Tera-electronvolt

¹Magnetic field: It is generated around the space of a moving charged particle.

²DNA structure: It is a compound of different molecules that provides information to cells functionality.

Answer from: Quest

An atom (ours, not carroll's) consists of a positively charged nucleus, surrounded by one or more negatively charged particles called electrons. the positive charges equal the negative charges, so the atom has no overall charge; it is electrically neutral. most of an atom's mass is in its nucleus; the mass of an electron is only 1/1836 the mass of the lightest nucleus, that of hydrogen. although the nucleus is heavy, it is quite small compared with the overall size of an atom. the radius of a typical atom is around 0.1 to 0.25 nanometres (nm), whereas the radius of a nucleus is about 10-6 nm. * if an atom were enlarged to the size of the earth, its nucleus would be only 200 feet in diameter and could easily rest inside a small football stadium.read more on -

Amichelson interferometer operating at a 600 nm wavelength has a 3.02-cm-long glass cell in one arm. to begin, the air is pumped out of the cell and mirror m2 is adjusted to produce a bright spot at the center of the interference pattern. then a valve is opened and air is slowly admitted into the cell. the index of refraction of air at 1.00 atm pressure is 1.00028.how many bright-dark-bright fringe shifts are observed as the cell fills with air?

It may seem strange that the selected velocity does not depend on either the mass or the charge of the particle. (for example, would the velocity of a neutral particle be selected by passage through this device? ) the explanation of this is that the mass and the charge control the resolution of the device--particles with the wrong velocity will be accelerated away from the straight line and will not pass through the exit slit. if the acceleration depends strongly on the velocity, then particles with just slightly wrong velocities will feel a substantial transverse acceleration and will not exit the selector. because the acc
