What are electric and magnetic fields interdependent?

Electric and magnetic fields are like best friends who always help each other out, when one moves or changes, the other has to react too.

Imagine you have a toy train that runs on tracks. The train is like an electric field, moving along the track. Now, if you suddenly switch on a light near the train, it creates a little magnetic field, kind of like a wave that spreads out from the light. This magnetic field can make the train feel something, just like how wind makes your hair move.

• If the electric field moves or starts going faster (like your toy train speeding up), it creates a magnetic field around it, kind of like how moving water in a river causes ripples.
• Then, if that magnetic field changes (like a ripple growing bigger), it can cause the electric field to move again, just like how ripples in water make waves that push more water forward.

They’re always helping each other out, and together they make things like electricity work in your house or even let you play with magnets and wires. It's like a fun dance between two best friends who can’t stop moving!
