Electronics and Communication Engineering (ECE) : Electromagnetic Field Theory - Quiz(MCQ)

Which of the following Maxwell equations use curl operation?

A)

Maxwell 1st and 2nd equation

B)

Maxwell 3rd and 4th equation

C)

All the four equations

D)

None of the above

Correct Answer : Option (A) : Maxwell 1st and 2nd equation

Explanation : Maxwell 1st equation, Curl (H) = J (Ampere law)

Maxwell 2nd equation, Curl (E) = -D(B)/Dt (Faraday’s law)

Maxwell 3rd equation, Div (D) = Q (Gauss law for electric field)

Maxwell 4th equation, Div (B) = 0(Gauss law for magnetic field)

It is clear that only 1st and 2nd equations use the curl operation.
