Questions & Step-by-Step Solutions

What is the principle behind electromagnetic induction?
  • Step 1: Understand that a magnetic field is an invisible 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 can create an electric field.
  • Step 3: Realize that this process is called electromagnetic induction.
  • Step 4: Know that the opposite is also true: a changing electric field can create a magnetic field.
