On the following website they indicate how powerful is a magnet by giving the theoretical maximum value of its adhesive force in kilograms or in Newton (its adhesive force at a distance of zero).
I would like to know how to convert this in tesla or in gauss.
More precisely, I would like to know how many tesla does a NdFeB magnet with a maximum adhesive force of 200 kg = 2000 N, a size of 10x10x1.5 cm and a mass of 1.3 kg generates at a distance of 50 cm ?
(I don't need a very accurate result. So if you can give me a rough approximation/estimation it will be good enough.)
