Q: What happens to the induced emf when the rate of change of magnetic flux increases? (2019)
Solution: The induced emf increases when the rate of change of magnetic flux increases, according to Faraday's Law.
Steps: 5
Step 1: Understand what induced emf is. Induced emf is the voltage generated in a circuit due to a change in magnetic flux.
Step 2: Learn about magnetic flux. Magnetic flux is the amount of magnetic field passing through a certain area.
Step 3: Know Faraday's Law. Faraday's Law states that the induced emf in a circuit is directly proportional to the rate of change of magnetic flux through the circuit.
Step 4: Recognize the relationship. If the rate of change of magnetic flux increases, it means that the magnetic field is changing more quickly.
Step 5: Apply Faraday's Law. Since the induced emf is proportional to the rate of change of magnetic flux, an increase in this rate will result in a higher induced emf.
