A magentic field is generated due to the movement of mobile or free electrons present.
These electrons spin in the same direction as a result current flows from low potential to high potential.
Therefore, we can conclude that out of the given options, the tiny magnetic effect of atoms within a domain is due to electrons that are unpaired and spinning in the same direction.
Platinum Gold and silver are used to make jewellery because of the following reasons. They are highly lustrous metals which are resistant to corrosion. They are highly malleable and ductile so can be transformed into any shape or design.
