Question:
What is the difference between a electric current and a electromagnetic wave?


Replies:
You get electric current when charges move from one place to another, on the other hand an electromagnetic wave is electromagnetic fields propagating in space - this propagation does not require presence of charges. Changing currents give rise to electromagnetic waves.
