Questions & Step-by-Step Solutions
According to Faraday's law of electromagnetic induction, the induced EMF in a circuit is directly proportional to the rate of change of which of the following? (2020)
Step 1: Understand what EMF means. EMF stands for electromotive force, which is the voltage generated by a circuit.
Step 2: Learn about Faraday's law of electromagnetic induction. This law explains how a changing magnetic field can create an electric current.
Step 3: Identify what 'rate of change' means. It refers to how quickly something is changing over time.
Step 4: Recognize that in this context, the 'rate of change' refers to the change in magnetic flux.
Step 5: Understand what magnetic flux is. Magnetic flux is the amount of magnetic field passing through a certain area.
Step 6: Conclude that according to Faraday's law, the induced EMF in a circuit is directly proportional to the rate at which the magnetic flux changes.
Faraday's Law of Electromagnetic Induction – The principle that the induced electromotive force (EMF) in a circuit is proportional to the rate of change of magnetic flux through the circuit.
