Can laser-induced graphene wires produce electromagnetic fields if a current is passed through them?

Question

For those who don't know, laser-induced graphene (LIG) is a porous type of graphene that appears after exposing certain types of carbon-based materials with a laser.

In this video, they made LIG on Kapton tape using a cheap 400 nanometer laser engraver module. He used the LIG to make supercapacitors, not to make conductive wires. At the end he used the LIG to make a low-voltage heater.

If I took a Kapton wire, turned it into a LIG wire, used the wire to make a coil and passed an electrial current (a DC current), would it generate an electromagnetic field?

Answer 1

The current through the coil will produce a magnetic field. The voltage across the coil that pushes the current through the coil will produce an electric field.
