Due to the age of the rock the magnetic field imbedded in it is often quite strong, considerably stronger than the earth's magnetic field today. It is interesting that many holy sites and healing spas were built near paramagnetic rock formations.he use of water treated by contact with paramagnetic soil is still in its infancy. However, agricultural experiments have clearly shown that both the paramagnetic soil itself (used as a fertilizer) and irrigation with paramagnetically treated water increase yields and plant vigour significantly(23).
