EMC Part 15. How to Cal the Degrade of Shielding Effectiveness with Magnetic / Inductive Coupling.
How to Calculate the Degrade of Shielding Effectiveness when Near to Magnetic H-Field.

Discussion on the Effectiveness of Shielding on Magnetic-Field Coupling with equations on 2 cases. 1) Non-magnetic Shield Grounded At Only One End and 2) Non-magnetic Shield Grounded At Both End.

Step by Step derive the equations of induce voltage from conductor 1 (noise source) to Conductor 2 (victim) with shielding.

Compare the 2 sets of equations: with shield and without shield at low and high frequencies so as to aware which methods or techniques to apply to resolve the problem.

From the equations, we study how we can maximize the use of shielding against Magnetic-field or Inductive coupling. We also conclude if the shielding is effective or not against Magnetic-field Coupling.
