Structure of electron: Electron has a standing- electric field and magnetic field in right angle regardless of any kind of its motions and act as a tiny bar magnet with a negative charge. (watch video Structure of electron). In an atom, the electric fields of its electrons will be directed to the nucleus and magnetic fields will be horizontal to the nucleus. (watch video Structure of atom) Magnetism is created when the magnetic fields of a number of electrons in a material become parallel. When the magnetic fields of a number of electrons in a cluster of atoms are become parallel, a magnetic domain is created. When the magnetic fields of two or more electrons in the atoms of a molecule are become parallel, a magnetic molecule is created. When electrons are flowing through a conductor, the magnetic fields of the flowing electrons are arranged in parallel and create a collective magnetic field around the conductor. Arrangement of electrons in a molecular magnet: Normally, the magnetic fields of electrons in atoms cancel each other and appear an atom cluster as non-magnetic. But in some molecules, because of the some special type of bonding between its atoms, the magnetic fields of two or more electrons in the molecule become parallel and these types of molecules exhibit molecular magnetism. The field strength of a molecular magnet is determined by how many electrons magnetic fields are parallel in the molecule. As the number of parallel magnetic fields is increases, the …
