Faraday’s law of electromagnetic induction is mathematically described by which one of the following equations?
- $\nabla\ \bullet \overrightarrow{B} = 0$
- $\nabla\ \bullet \overrightarrow{D} = \rho_V$
- $\nabla\ \times \overrightarrow{E} =\ – \large\frac{\partial\!\: \overrightarrow{B}}{\partial t}$
- $\nabla\ \times \overrightarrow{H} =\ \sigma\: \overrightarrow{E} + \large\frac{\partial\!\overrightarrow{D}}{\partial t}$
