is the north and south correctly marked? I have other magnets marked and the coster seems wrongly marked

Southpole is the blue circles and is for stimulating and energy. North Pole for calming and relaxing.

Is one side South facing and the other North . Thanks in advance

Yes - This is clearly marked on the coaster.

how many years does this magnetic coaster last shelf life on magnets that is before they cease working

10 years for that amount of Gauss.

what are the dimensions of this magnet? how strong is the Guass rating and what is the grade of the magnet?

I have only recently thrown the pack out but I can tell you it is approx 11 cms in diameter. The link below may be the same one and does give some info.http://norstar-biomagnetics.co.uk/product/the-water-coaster/
