Parallel and Anti-parallel Currents This short analysis offers an interpretation of the magnetic force between two parallel conductors without invoking the magnetic field vector, the right hand rule, or the Lorentz force.  It is in no way intended to minimize the importance of these tools for the practical analysis of magnetic effects.  The intent is to give the reader another perspective and some insight into why the magnetic field is now viewed as a modification of the electric field.  It also reinforces the intricate involvement of the speed of light with both electric and magnetic phenomenon.   The magnetic force per unit length between two long straight parallel  conductors is given by the equation: where   is the permeability of space. Multiplying both numerator and denominator by the permittivity constant, Recognizing that; We can write the force per unit length as: Charged particles interact, or  communicate , at the speed of light...

Electron magnetic  moment                    by ;-)#awesomeboy_atulraj In  atomic physics , the  electron magnetic moment , or more specifically the  electron magnetic dipole moment , is the  magnetic moment  of an  electron  caused by its intrinsic properties of  spin  and  electric charge . The value of the electron magnetic moment is approximately  −9.284 764 × 10 −24   J / T . The electron magnetic moment has been measured to an accuracy of 7.6 parts in 10 13 Magnetic moment of an electron [ edit ] The electron is a  charged particle  of charge −1 e , where  e  is the  unit of elementary charge . Its  angular momentum comes from two types of rotation:  spin  and  orbital motion . From  classical electrodynamics , a rotating  electrically charged  body creates a  magnetic dipole  with...

What inside a magnet gives it it's property of attraction?      by;-)awesomeboy_atulraj Magnets work because of the quantum mechanical property of  Electrons. In the atomic level, all material contains protons and electrons. Each of these fundamental particles are magnets on their own. Especially the electron, has a fundamental property of dipole-moment, other than bearing a charge, that makes it a small magnet. In the same sense, a proton is a small magnet too, but not as powerful as the electron is. The dipole moment, which makes the electron behave like a magnet, is in turn, a consequence of an even more fundamental property called  spin . The spin, being a quantum property, can exist in only two states, resulting in either  up  or  down  pointing magnetic fields. This is most contributing property as to why magnets are  magnetic . In an atom, the electrons are whizzing around, but confined in shells. These shells can be eit...
