NSE 508 EM Lecture #3 3 Divergence of B -Field The B-field is solenoidal , i.e. the divergence of the B- field is identically equal to zero: From gauss theorem field lines are closed. Physically, this means that magnetic charges (monopoles) do not exist. A magnetic charge can be viewed as an isolated magnetic pole. 0 B    VS divAdV A n ds   
