Questions & Step-by-Step Solutions

What is the phenomenon called when a changing magnetic field induces an electromotive force (EMF) in a conductor?
  • 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 a conductor is a material that allows electricity to flow through it, like copper wire.
  • Step 4: Realize that when a changing magnetic field passes through or around a conductor, it can cause electrons in the conductor to move.
  • Step 5: This movement of electrons creates an electromotive force (EMF), which is a voltage that can drive an electric current.
  • Step 6: The overall process of a changing magnetic field causing this effect in a conductor is called electromagnetic induction.
