Question 46

Lenz’s law of electromagnetic induction states that

  • A.electromotive force is induced in a circuit whenever there is a change in the magnetic flux linked with the circuit
  • B.the induced current in a conductor is in such a direction as to oppose the change producing it
  • C.the induced e.m.f. in a circuit is proportional to the rate of change of number of lines of force linking the circuit
  • D.a force is exerted on a current carrying conductor in a magnetic field
  • E.the induced e.m.f. is proportional to the current producing the magnetic flux.
