(1) i was saying that spin is just the direction pointer of the produced magnetic field.
(2) it tells just whether the magnetic field produced will align with the magnetic field of others.
(3) this twofacts were evident from neutrons as neutrons have spin but no magnetic field.
That's not correct. The DIRECTION of the spin is what tells how it aligns with an external magnetic field. Neutrons also have a magnetic moment. (A magnetic field) Spin is much more than you are making it out to be.
