The electron e- is a negatively charged elementary particle. In the standard model, it is classified as a member of the lepton family. As a very simple particle, it has no inner structure and a mass of about 1/1840 the mass of the proton. The electron has been heavily described using quantum mechanical theory. One very important result is that an electron can be described by various quantum numbers. Importantly, the spin quantum number assigns unique properties to every electron in an atom The electron is responsible for many properties of matter. They constitute the electric current, are responsible for chemical bonding and reactions, impart color to substances, conduct heat, and give rise to magnetic properties. We know from electromagnetic theory that a moving charge generates magnetic fields. Therefore, electrons as individual entities are magnets in their own right. We shall see in this article how electrons behave like magnets and how magnetic behavior arises. I have tried as muc

  The field of magnetohydrodynamics has proven to be a very interesting one. It involves the study of electrically charged fluids and their interaction with magnetic energy. In this model, the motion, flow and dynamics of charged fluids such as liquid metals, electrolytes, and plasma are studied in their interactions with magnetic fields. Today we can admit that magnetohydrodynamic phenomena are very important on Earth and elsewhere in the universe. You might have read or heard that there exists a magnetic field in the earth’s core that shields and protects us from the hazardous solar wind. This magnetic field is due to magnetohydrodynamics. The iron in the earth’s core generates this field creating a magnetic dipole and thereby deflecting the solar radiation. This leads to a distortion of the field lines as shown in the picture above. This is the basis of the protective effect of the magnetic field. Also the complex system which exists in the sun is a very interesting case of a MHD sy
