Linear Polarization: Magnetic Field Effects

Click For Summary
SUMMARY

During linear polarization, the electric field (E-field) direction defines the polarization state, while the magnetic field (B-field) remains perpendicular to the E-field. In a vacuum, the B-field is at right angles to the E-field, but this relationship can vary when interacting with matter. The amplitude of the B-field fluctuates in phase with the E-field, maintaining a right-angle orientation to both the E-field and the direction of wave propagation.

what happens to the magnetic field during linear polarization and what happens exactly?
 
Science news on Phys.org
Well, "polarization" usually refers to the direction the E-field is pointing. In a vacuum, the B-field would be perpendicular to the E-field, but in matter, this is not strictly the case.

The magnetic field will be at right angles to the electric field and will vary in amplitude in phase with the Electric field. Both field vectors will be at right angles to the direction of propagation of the wave.
