| Abstract: | This paper point out that the self-energy of an isolated charged body is equal to the sum of the mutual energy that consists in amount inside charge elements,and that the sum of self-energy of all charge elements is equal to zero;The magnetic energy of a self-inductance of a limited distributed current loop is equal to the sum of the magnetic energy of mutual inductance that consists in amount inside sub-current loops,and the sum of magnetic energy of a self-inductance of all sub-current loops is equal to zero. |
