Molecular magnetism

   Today we believe that moving electric charges and intrinsic spin of electric charges produce magnetic field; in fact the belief is that there is a direct connection between motion of charges and magnetic field. But new studies indicate that, a charged particle like electron has a standing electric field and magnetic field at right angle simultaneously (see structure of electron) and motion of a charged particle has no effect on its electric or magnetic property. Each electron acts as a tiny magnet. When electrons flow in a conductor, the "electron magnets" will be aligned and this alignment creates a collective magnetic field around the conductor. The flow of electrons make them get aligned, otherwise there is no any direct connection between motion of electrons and the creation of magnetic field as per the current belief.
   In an atom because of the positive charge of the nucleus, the electric field of an electron will be directed to the nucleus and magnetic field will be horizontal to the nucleus (see structure of atom). Normally the magnetic fields of electrons in a cluster of atoms is neutralised to each other and the cluster creates little or does not create net magnetic field around it. But in some atom cluster because of some special type of bonding between its atoms, a number of electron"s magnetic fields come parallel. Such atom cluster produces a magnetic field around it and becomes a magnetic domain. Similarly in some molecules because of the similar kind of bonding between its atoms, two or more electron's magnetic fields become parallel and that region becomes a pole and the molecule becomes magnetic.
