In a generator, what is the role of the rotating coil? (2022)
Steps
Concepts
Step 1: Understand that a generator converts mechanical energy into electrical energy.
Step 2: Know that the generator has a coil of wire that can rotate.
Step 3: Recognize that the coil is placed in a magnetic field.
Step 4: Learn that when the coil rotates, it changes the amount of magnetic field lines passing through it.
Step 5: Realize that this change in magnetic field lines creates an electric current, known as EMF (Electromotive Force).
Step 6: Conclude that the rotating coil is essential because it is responsible for inducing the EMF by changing the magnetic flux.
