← ScienceWhich mechanism causes induced current when a toroidal coil's magnetic resistance is abruptly modified?
A)Faraday's law of induction✓
B)Lenz's law of direction
C)Coulomb's law of repulsion
D)Ampère's circuital propagation
💡 Explanation
A changing magnetic field induces a voltage because Faraday's law of induction relates changing magnetic flux to induced electromotive force, therefore current flows. That law works, rather, than Lenz's determining the direction or Coulomb’s governing static charge interaction.
