Which of the following describes Faraday's law of electromagnetic induction?
ALike poles repel each other
BInduced EMF is proportional to the rate of change of magnetic flux
CResistance increases with length
DCurrent flows from higher potential to lower potential
✓ Correct Answer: B — Induced EMF is proportional to the rate of change of magnetic flux
Faraday discovered that changing the magnetic field through a coil induces a voltage (EMF) proportional to how fast the field changes.
