In this section, we generalize Kirchoff’s Voltage Law, previously encountered as a principle of electrostatics, which states that in the absence of a time-varying magnetic flux, the electric potential...In this section, we generalize Kirchoff’s Voltage Law, previously encountered as a principle of electrostatics, which states that in the absence of a time-varying magnetic flux, the electric potential accumulated by traversing a closed path C is zero.
Curl is an operation, which when applied to a vector field, quantifies the circulation of that field. The concept of circulation has several applications in electromagnetics.
