I dont know how to add magnetic field in lammps

Hi
I want to add magnetic force in my simulation with lammps.
I saw in mailing bow of lammps that you had said about this question:
"yes - if you use fix efield as a starting
point to create fix bfield, you will see that
it is possible to specify a spatially and time
dependent magnetic field, that you could
then apply to generate a force based on
the charge and velocity of each atom."

What did you mean about “fix bfield”?
I saw only “fix efield” command in lammps manual that only impose Electric field.

thanks alot

who is "you"?

I saw only "fix efield" command in lammps manual that only impose Electric
field.

it means, that many people have asked to
have a "fix bfield" implemented, but nobody
either cared enough or was willing to spend
the time to actually implement it, or implemented
it, but didn't care (or want) to share it.

if you want a fix bfield, you will have to
program it, or sponsor somebody to do
it for you.
