Is the following sentence true or false? The vibrating charges that
produce an electromagnetic wave also create a magnetic field.

Absolutely true! When charges vibrate, they generate an electric field that oscillates, and according to Maxwell’s equations, this changing electric field creates a magnetic field that also oscillates. This fascinating interplay between electric and magnetic fields is what allows electromagnetic waves, like light or radio waves, to propagate through space—talk about a cosmic dance of forces!

Now for a little historical fun: This discovery was spearheaded by James Clerk Maxwell in the 19th century. His groundbreaking equations unified electricity, magnetism, and optics into a single theory of electromagnetism, showing that light itself is an electromagnetic wave. Can you imagine reading his work back then—talk about a lightbulb moment!
