Laboratory Exercises to Accompany Chapters 10-12

These demonstrations and laboratory exercises illustrate concepts described in Electromagnetic Compatibility Course Notes


magnetic shielding test fixture
Chapter 10: Low-frequency Magnetic-field Shielding

At low frequencies, magnetic field shielding materials redirect the field using magnetic materials.
Laboratory Exercise 23: Low-frequency Magnetic-field Shielding


Chapter 10: High-frequency Magnetic-field Shielding

At high frequencies, magnetic fields can be redirected by the eddy currents in conductive materials.
Laboratory Exercise 24: High-frequency Magnetic-field Shielding


Chapter 10: Electric-field Shielding

Conductive materials can stop electric fields at virtually any frequency. Unlike magnetic-field shields, how and where an electric-field shield is grounded can be very important.
