Q: Faraday's law of electromagnetic induction states that the induced EMF in a circuit is proportional to what? (2019)

Solution: Faraday's law states that the induced EMF is proportional to the rate of change of magnetic flux.

Steps: 5

Step 1: Understand what EMF means. EMF stands for electromotive force, which is the voltage generated by a circuit.
Step 2: Learn about magnetic flux. Magnetic flux is the measure of the amount of magnetic field passing through a certain area.
Step 3: Know that Faraday's law relates EMF to changes in magnetic flux. It tells us how much voltage is produced when the magnetic field changes.
Step 4: Remember that the key part of Faraday's law is the 'rate of change.' This means how quickly the magnetic flux is changing over time.
Step 5: Conclude that according to Faraday's law, the induced EMF in a circuit is proportional to how fast the magnetic flux is changing.
