DEFINE_SOURCE to redifine momentum and energy equations.

I would like to write UDF (Fluent 12.1) in which I can add j*B to momentum equations in order to simulate interior magnetic fields in my conducting fluid. I have read that I should use DEFINE_SOURCE macro in order to do this.
Flowing electric current through fluid creates magnetic field which have an impact on fluid and I want to simulate this by improving momentum and energy equations. Does anyone have any clues for me how to do it?
I suppose I have to loop over all cells and need current density from fluent in order to calculate B. , is that right?
I have not seen macro which can pass to me value of density of current in a cell.
I would appreciate any response.
