Separating Electricity and Magnetism from EM Waves

Click For Summary
SUMMARY

The discussion centers on the impossibility of separating electric and magnetic fields from electromagnetic (EM) waves without destroying the wave itself. It is established that Maxwell's equations unify these components, and Jefimenko's Equations illustrate their coupling. Removing either field component results in the breakdown of the electromagnetic wave, although decoupling can occur at very low frequencies with minimal impact on the other field over certain distances.

PREREQUISITES
  • Understanding of Maxwell's Equations
  • Familiarity with Jefimenko's Equations
  • Knowledge of electromagnetic wave propagation
  • Basic concepts of electric and magnetic fields
NEXT STEPS
  • Study Maxwell's Equations in detail
  • Explore Jefimenko's Equations and their applications
  • Research the behavior of electromagnetic waves at low frequencies
  • Examine the principles of electromagnetic field coupling
USEFUL FOR

Physicists, electrical engineers, and students studying electromagnetism who seek to deepen their understanding of the relationship between electric and magnetic fields in electromagnetic waves.

Electricity and magnetism had been unified under Maxwell's four famous equations. But I wonder if there any method to separate the this two components from an EM wave?

Will there be any effects if this two components are separated?

Hope you all can help me to solve this problem^^

Thank you for kind assistance :)

No. If you were to "remove" (that is zero out the field) either the electric or the magnetic field component from an electromagnetic wave then you end up destroying the wave. If you want to see how the two are coupled explicitly, you can look at Jefimenko's Equations. Jefimenko's Equations show the excited electric and magnetic fields from a given set of sources. Any time-varying sources produce both electric and magnetic fields. If you were to "remove" one of these components the electromagnetic field has to break down. The two fields do become decoupled at very low frequencies and here you could destroy one of the fields without too severely affecting the other (over a reasonable set of distance).
