    Question

    Which of the following is not the Maxwell's equation?

    A.

    divD=ρ\operatorname{div} \vec{D}=\rho​​

    B.

    divB=μ0 J\operatorname{div} \overrightarrow{\mathrm{B}}=-\mu_0 \overrightarrow{\mathrm{~J}}​​

    C.

    curlE=Bt\operatorname{curl} \overrightarrow{\mathrm{E}}=\frac{-\partial \overrightarrow{\mathrm{B}}}{\partial \mathrm{t}}​​

    D.

    curlH=J+Dt\operatorname{curl} \overrightarrow{\mathrm{H}}=\overrightarrow{\mathrm{J}}+\frac{\partial \overrightarrow{\mathrm{D}}}{\partial \mathrm{t}}​​

    Correct option is B
