Electromagnetic coupling between filaments in multifilament coated conductor with finite transverse conductance between filaments was studied numerically and experimentally. We are particularly interested in coupling time constants. The important characteristics of the conductors such as finite electric field – current density characteristics as well as transverse conductance can be determined by the comparison between calculated and measured temporal behaviors of magnetic fields and coupling time constants. The analyzed and measured object include short pieces of conductor, pancake coil, and cables.
