Math & Science ⇒ bold greek character and letter in equation

[itb1000]

Hi,
I would like to get I, \sigma and B_0 in bold in this equation:

Code: Select all

\begin{equation}
H_\mathrm{CS} = -\gamma I \sigma B_0
\end{equation}

If I use \boldmath in this way:

Code: Select all

\begin{equation}
H_\mathrm{CS} = -\gamma \boldmath{I \sigma B_0}
\end{equation}

everything is in bold (also H_\mathrm{CS} = -\gamma).

When I use \mathbf:

Code: Select all

\begin{equation}
H_\mathrm{CS} = -\gamma \mathbf{I \sigma B_0}
\end{equation}

I and B_0 are bold but not \sigma.

You can I selectively get I, \sigma and B_0 in bold?
Please help me!!!

Hi Thierry,

use \boldsymbol of amsmath:

Code: Select all

H_\mathrm{CS} = -\gamma \boldsymbol{I \sigma B_0}

Hi Stefan,
thanks for your help.
\boldsymbol is working well.
