← ScienceWhich mechanism generates an electromotive force (EMF) in a coil rotating within a static magnetic field?
A)Faraday's law of induction✓
B)Coulomb's law of electrostatic force
C)Ampère's circuital law
D)Ohm's law conductivity
💡 Explanation
When a coil rotates, the magnetic flux through the coil changes, inducing an EMF according to Faraday's law of induction because the rate of change of magnetic flux is proportional to the induced EMF. Therefore, EMF is generated, rather than electrostatic force effects, current effects, all which depend on different electromagnetic parameters.
