Is my wok carbon steel (it is magnetic)and how do I proceed - seems I am ruining it
Dollars to doughnuts, the film you have been fighting so valiantly to get off there is polymerized vegetable oil - aka "seasoning." The odds that it was coated with anything else are quite low.

Since you're well into having destroyed whatever seasoning it had, go ahead and burn off whatever is left (place in oven on "self-clean" cycle, or place in a wood fire) or else attack it with abrasives such as steel wool or sandpaper (stick to fairly fine sandpaper or you're going to need to run through several grades of finer sandpaper to get the surface back to usable/smooth if you scratch it up with coarser stuff).

You can also try running it through the dishwasher - harsh dishwasher detergents will often strip seasoning.
