Once the degaussing coil is in position, it''s time to supply it with an electric current.
Using a permanent magnet as an electromagnet core
As I said, to demagnetize one you need a gently decaying train of alternating pulses. I am not sure how you got "a pulse" from that. Heating to the Curie temperature will destroy any existing magnetism, cooling in the presence of an external magnetic field will re-magnetize it that way; it''s how rocks get magnetized.
