Q
Q: According to Faraday's law, the induced EMF in a circuit is proportional to what?
Solution: Faraday's law states that the induced EMF is directly proportional to the rate of change of magnetic flux through the circuit.
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 amount of magnetic field passing through a certain area.
Step 3: Know that Faraday's law relates EMF to magnetic flux. It tells us how changes in magnetic flux can create voltage in a circuit.
Step 4: Recognize that the key part of Faraday's law is the 'rate of change' of magnetic flux. 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 directly proportional to how fast the magnetic flux is changing.
