Question 8:
• ________: From Faraday's law of induction, the changing magnetic field can induce circulating loops of electric current in the conductive metal core.
Eddy currentElectromagnetismElectromotive forceMaxwell's equations

Question 9: ________ through the conductor creates a magnetic flux proportional to the current, and a change in this current creates a corresponding change in magnetic flux which, in turn, by Faraday's Law generates an electromotive force (EMF) that opposes this change in current.
