Answer:
magnetic flux lines
Explanation:
When a conductor cuts across magnetic flux lines, the amount of the voltage induced depends on the **magnetic flux lines**. The other factors listed—mutual induction, self-induction, and induced current—are related concepts in electromagnetism but do not directly determine the amount of voltage induced by the cutting action of the conductor through the magnetic field. The induced voltage is directly proportional to the rate of change of the magnetic flux linkage.
