## Main Question or Discussion Point

I recently read that Maxwell's equations can be written in a more concise form as the following:

[tex]\nabla\times\vec{M} = \frac{-i}{c}\frac{\partial\vec{M}}{\partial t}[/tex]

[tex]\nabla\cdot\vec{M} = 0[/tex]

where [tex]\vec{M} = c\vec{B} + i\vec{E}[/tex].

Why is this form not popular?

[tex]\nabla\times\vec{M} = \frac{-i}{c}\frac{\partial\vec{M}}{\partial t}[/tex]

[tex]\nabla\cdot\vec{M} = 0[/tex]

where [tex]\vec{M} = c\vec{B} + i\vec{E}[/tex].
