A mass spectrometer measures atomic mass by removing one or more electrons from an atom. The spectrometer then sends the atom through a magnetic field. Because of the missing electrons, the atom has more protons than electrons, resulting in a positive charge. The magnetic field bends the path of the positively charged atom as it moves through the field. The amount of bending depends on the atom's mass. The atomic mass of the atom can be calculated from the magnitude of the bend.
Iron is a paramagnetic substance.so when a magnetic field is applied the molecules align itself in the direction of field.There may be other paramagnetic substances like iron.But diamagnetic substances are difficult to magnetise
Even a single atom (if it is the right kind of atom) can generate a magnetic field, so there can be any number of atoms in a magnet, from one onwards to very large numbers, such as 1025.
Valence electrons are the electrons in the outermost shell of an atom. These electrons are important in bonding and magnetism. For example, carbon has 4 valence electrons. It can make 4 covalent bonds to fulfill the octet rule. Also, if an atom has unpaired electrons, it is called paramagnetic and if an external magnetic field is applied, it will be attracted. If all of the electrons are paired, it is diamagnetic and will be repelled by an external magnetic field.
Polar orientation is defined as being the moment in which electric dipole is induced in a system such as that of an atom or molecule. This induction is completed through the use of an electric field of unit strength.
Every atom with the electron(s) revolving - or "spining" - around the atom's nucleus is a little magnet itself. Electrons of all atoms in a piece of material revolve (spin) in all possible directions, the magnetic field produced be each atom-magnet cancel each other and there is no general magnetic field in the material. If under the influence of an external magnetic flux picture does not change the material is said to be non-magnetic. On the contrary, if under the influence of the external magnetic flux the electrons spinning allign in the direction of the flux, the magnetic field of every atom allign too and produce a general magnetic field - the material is magnetic.
There is no Larmor precession without magnetic field

The electrons in the atoms are in an electromagnetic field. This field determines the velocity, length, and shape of orbit in which they spin around the nucleus.
Both magnetic materials and moving electric charges induce magnetic fields. "A magnetic field can be created with moving charges, such as a current-carrying wire. A magnetic field can also be created by the spin magnetic dipole moment, and by the orbital magnetic dipole moment of an electron within an atom." A magnetic field can be produced by either a permanent magnet, or an electromagnet, the latter requiring suitable energization to function.

Simple Answer:An isolated atom has three sources for a magnetic field, the electron motion, the electrons' intrinsic magnetic moment and the nuclear magnetic moment.Explanation:First, the electrons around the atom are in motion and if there is a net circulating flow (i.e. a nonzero angular momentum) then the motion of the electrons is a current that produces a magnetic field in basically the same process that any current produces a magnetic field.Second, the electron itself has a magnetic property as a particle called the magnetic moment. The magnetic moment of the particle effectively makes it a tiny permanent magnet. (Other elementary particles have this property also.) The electrons in an atom can be arranged so that the magnetic fields of the individual electrons' magnetic moments add together or cancel each other out. If they do not totally cancel each other out, the atom as a whole then has the property of a tiny magnet. If arranged in a bulk form, like an iron magnet, these electrons can be the primary source of the permanent magnetic field of a material.Third, the nucleus of an atom is also made up of particles with an intrinsic magnetic moment, just as the electron is. In particular, the protons have a large magnetic contribution. It is not often the case that the nuclei of atoms spontaneously align with the nuclei of other atoms to produce a net permanent magnetization of a material, but it is a technologically important characteristic, e.g. for magnetic resonance imaging (MRI).

This depends if they are charged or neutral and if they are moving or not. A: If they are not moving then nothing usually and if they are neutral nothing. B: If they are charged and moving then they begin to accelerate in the direction of the magnetic field. C: If the object is a magnetic object for instance Iron that shares its electrons metallically then it will feel a acceleration in the direction of the magnetic field all other object will feel nothing.
If a magnet doesn't stick to a material, that means that the material is non-magnetic. Every individual atom is a magnet, but in a magnetic material, there are groups of atoms (called "magnetic domains") that have their magnetic directions aligned. An outside magnetic field in such materials will align some of the magnetic domains in the direction of the magnetic field.
A magnet is produced at the atomic level, the atoms that make up magnetic material have a "valence" electron configuration that causes the atom to have a positive and negative pole, these when are placed next to atoms of the same orientation will cause a uniform magnetic field and also the domains line up to make the magnetic field
