%X The generalized principle of least action in electromagnetism is presented, which is effective even though in lossy and nonreciprocal media. It is pointed out that the Maxwell’ s equations can be derived from this principle. At last for example of its applications, some useful variational expressions for electromagnetic fields are derived systematically from the principle.
