In electromagnetic induction, what is the role of the changing magnetic field?

Step 1: Understand that a magnetic field is an invisible force created by magnets or electric currents.
Step 2: Recognize that when the strength or direction of a magnetic field changes, it is called a 'changing magnetic field.'
Step 3: Know that a conductor is a material that allows electricity to flow through it, like copper wire.
Step 4: Learn that when a changing magnetic field passes through a conductor, it creates an electromotive force (EMF).
Step 5: Understand that this EMF causes electrons in the conductor to move, which creates an electric current.
Step 6: Conclude that the changing magnetic field is essential because it is what starts the process of generating electricity in the conductor.
