1476 - How are changing magnetic fields and electric fields related to each other?

Changing magnetic fields and electric fields are related through a process called electromagnetic induction.

Imagine you have a magnet and a coil of wire. When you move the magnet near the coil, you create a changing magnetic field. This changing magnetic field then creates an electric field in the coil, which can make electricity flow.

The reverse is also true: when an electric field is changing, it can create a magnetic field. So, they kind of "cause" each other to appear and change.

This relationship is really important in things like generators, which use magnets to create electricity, and motors, which use electricity to create movement.
