Questions & Step-by-Step Solutions
Which law states that the induced electromotive force (emf) in a closed circuit is proportional to the rate of change of magnetic flux through the circuit?
Step 1: Understand what induced electromotive force (emf) means. It is the voltage generated by changing magnetic fields.
Step 2: Learn about magnetic flux. It refers to the amount of magnetic field passing through a surface.
Step 3: Know that when the magnetic flux changes, it can create an electric current in a closed circuit.
Step 4: Identify the law that describes this relationship. It is called Faraday's law.
Step 5: Remember that Faraday's law states that the induced emf is proportional to how quickly the magnetic flux changes.
