I have a problem with \vec command: instead of the vector symbol it inserts the tilde. I don't see what part of the code is wrong: $$\mathbf{\Gamma(\vec{B}) = \mu_0 I + \frac{d\phi(\vec{E})}{dt}}$$.

    I don't get any tilde, though your code is strange in many ways (do you really want vectors both bold and with an arrow?) Please provide a short minimal code reproducing the issue, and maybe explain how the equation is supposed to look like.

    Welcome to TeX.SE! Please provide complete small document, which reproduce your problem. In my math testbed (used stix fonts doesn't reproduce your problem. BTW, $$ is not LaTeX instruction, rather TeX primitive. Please use \[ and \] instead or \begin{equation*} ... \end{equation}

    What's the reason for the \mathbf encompassing the whole formula?

The reason is \mathbf encompassing the whole formula, which is wrong and makes no sense whatsoever, because it doesn't make the formula bold, but just uses various symbols without a proper meaning.

If you want to make a formula bold for emphasizing it (but you shouldn't), use \bm.



\bm{\Gamma(\vec{B}) = \mu_0 I + \frac{d\phi(\vec{E})}{dt}}


enter image description here

Note, however, that boldface in math doesn't carry the meaning of emphasis.

  • Thank you very much, effectively I can remove the boldface. Jun 15 at 9:39
