Question

Question:
Would electromagnetic waves exist if changing magnetic fields couldproduce electric fields, but changing electric fields could not inturn produce magnetic fields?

My guess:
I think they would not exist because this field induction loop (ifthat's the right term) is required for the wave to propagate. Ibelieve the answer is 6.

CHOICES
1. Yes; electromagnetic waves consist of either electric ormagnetic fields, but not necessary both.
2. Can’t be determined unless we know the propagation mediumof the electromagnetic waves.
3. More information is needed.
4. Yes; only the magnetic field changes in electromagneticwaves.
5. Yes; as long as we have a magnet, there is a magnetic field toform the electromagnetic waves.
6. No; electric and magnetic fields coexist in electromagneticwaves by field induction.

Explanation / Answer

No; electric and magnetic fields coexist in electromagnetic waves by field induction
