Question
Faraday’s law of electromagnetic induction is mathematically described by which one of the following equations?
Correct answer
(C) × E = -∂ B∂ t
Solution
Faraday's law of induction in differential form states that the curl of the electric field is equal to the negative of the time rate of change of the magnetic flux density:Other options represent different Maxwell's equations:
(A) Gauss's law for magnetism:
(B) Gauss's law for electricity:
(D) Ampere-Maxwell law: , where is the conduction current density.
