Faraday's Law of Electromagnetic Induction Quiz

What is the basis of Faraday's law of electromagnetic induction?

• Change in electric field

• Change in light intensity

• Change in magnetic field

• Change in gravitational field

What is the formula associated with Faraday's law of electromagnetic induction?

• Induced emf = n * change in current

• Induced emf = n * change in voltage

• Induced emf = n * change in flux / change in time

• Induced emf = n * change in resistance

How can you induce an emf by changing the flux in a coil?
