When any special science proposition is discussed,it is always necessary to primarilyconstruct a finite discourse universe or discussion domain,which maybe coincides in somedegree with the category said by Cant. Of course,the finite domain of a theoretica...[继续阅读]

    Besides,another prerequisite problem we should primarily solve will rest with how toexactly identify the real physical connotation of a given current distribution J(x,t),which isone of the two independent variables in the formal system. When another indep...[继续阅读]

    We will find lots of concept confusions or logic paradoxes to universally exist in theclassical theorem. Or,accompanied with the knowledge on forms of electromagnetic phenomenadeveloping wider and deeper,the classical theorem has lacked of a through logic...[继续阅读]

    As a universal principle in physics,charge would neither die nor be born. Then,according to the universal charge conservation equation,once a current distribution J(x,t),which logically corresponds to a moving charge set,presented an arbitrarily given spa...[继续阅读]

    Perhaps,lots of readers all knew that,when given the Maxwell’s equation set to certainlysatisfy with a necessary solvability requirement,the unique ground of the judgement in logicmight be that the numbers of variables and equations equal each other in Ma...[继续阅读]

    Without doubt,it is needed to make a historic and systemic consideration and analysis,when we logically rearrange the classical theorem. Though so is it,we might still reasonablyaffirm that,provided really only following rationality,not clinging or adheri...[继续阅读]

    Not only so is that,even though Maxwell’s equation set has been suitably divided as twomaybe independently existing subsystems,each of which can only logically rely upon apermissibly singularly given source,ρ(x) or J(x,t),the problem inconsistent in logic...[继续阅读]

    We should fixedly remember that,restricted within the finite discourse domain of classicalelectromagnetism,there are two independent sources to possibly excite electromagnetic field or akind of electromagnetic effects. Or,so as clearly proposed in the ver...[继续阅读]

    Supposed,it may always be permissibly to freely use electromagnetic field as a specialappellation to formally express the form of one of really existing material realities. Even thoughso is it,we can never forget such a particular material existence to no...[继续阅读]

    According to the classical electrodynamics,in a given electromagnetic field,which isexpressed by E and B,the electromagnetic force F acting on a moving charged particle withcharge e and velocity v isF=e(E+v×B) (1.3.4)The formula is the famous Lorentz-forc...[继续阅读]
