Questions & Step-by-Step Solutions
A changing magnetic field induces a current in a closed loop. What is this phenomenon called?
Step 1: Understand that a magnetic field is an area around a magnet where magnetic forces can be felt.
Step 2: Learn that when the strength or direction of a magnetic field changes, it creates a change in the magnetic environment.
Step 3: Know that this change in the magnetic field can affect nearby conductors, like wires.
Step 4: Realize that when a conductor is placed in a changing magnetic field, it can cause electrons in the conductor to move.
Step 5: This movement of electrons creates an electric current in the conductor.
Step 6: The process of generating an electric current from a changing magnetic field is called electromagnetic induction.
Electromagnetic Induction – The process by which a changing magnetic field creates an electromotive force (EMF) in a conductor, leading to the induction of current.
