What happens to the induced EMF if the rate of change of magnetic flux is doubled?
It remains the same
It doubles
It halves
It quadruples
According to Faraday's law, the induced EMF is directly proportional to the rate of change of magnetic flux. Therefore, if the rate is doubled, the induced EMF also doubles.

Q: What happens to the induced EMF if the rate of change of magnetic flux is doubled?
Solution: According to Faraday's law, the induced EMF is directly proportional to the rate of change of magnetic flux. Therefore, if the rate is doubled, the induced EMF also doubles.
Steps: 5
Step 1: Understand what induced EMF is. It is the voltage created when the magnetic field around a conductor changes.
Step 2: Learn about Faraday's law. It states that the induced EMF is directly related to how fast the magnetic flux changes.
Step 3: Identify the term 'rate of change of magnetic flux.' This means how quickly the magnetic field is changing.
Step 4: If the rate of change of magnetic flux is doubled, it means the magnetic field is changing twice as fast.
Step 5: Since induced EMF is directly proportional to the rate of change, if the rate is doubled, the induced EMF will also double.
