Prof. Filippo Capolino ECE Dept. Fall 2006 Notes 27 ECE 2317 ECE 2317 Applied Electricity and Magnetism Applied Electricity and Magnetism Notes prepared by the EM group, University of Houston . (used by Dr. Jackson, spring 2006) Mutual Inductance Mutual Inductance ± 2 n ± 1 n I 1 I 2 Two coils are in proximity of each other. Current reference directions and unit normals are defined on both coils (The unit normals are determined from the current reference directions, by the right-hand rule.) Mutual Inductance (cont.)
