Questions & Step-by-Step Solutions
According to Faraday's law, the induced electromotive force (emf) in a closed loop is proportional to what?
Step 1: Understand that Faraday's law deals with electromotive force (emf) in a closed loop.
Step 2: Know that emf is the voltage generated by changing magnetic fields.
Step 3: Recognize that 'induced' means that the emf is created due to a change in something else.
Step 4: Identify that the 'magnetic flux' refers to the amount of magnetic field passing through the loop.
Step 5: Learn that the 'rate of change' means how quickly the magnetic flux is changing over time.
Step 6: Conclude that according to Faraday's law, the induced emf is proportional to how fast the magnetic flux changes.
Faraday's Law of Electromagnetic Induction – Faraday's law states that the induced electromotive force (emf) in a closed loop is proportional to the rate of change of magnetic flux through that loop.
