How can COMSOL AC/DC module simulate a Current Source?

How can COMSOL AC/DC module simulate a Current Source?
As it is described in Wikipedia, "A current source is an electronic circuit that delivers or absorbs an electric current which is independent of the voltage across it."

Now I have the Current history profile I(t), and I want to add it to the two ends of the load (may be an inductor) and conduct a transient simulation.

How can I make it? Can the Single Turn Current Domain or Multi Turns Current Domain be used to simulate in transient problem?
Or if I use the Lumped Port, is the current defined in Lumped Port the one that really run through the load? I mean the induced current in the inductor can be neglected.
