Origin : The name is derived from the Latin ‘magnes’, magnet.
Description :
A hard, brittle, silvery metal used to harden steel. It is an essential element for all living things. Certain soils are deficient in it, and so it is added to some fertilisers and given as a food supplement to grazing animals. The average human body contains about 12 milligrams and takes in about 4 milligrams per day from such foods as nuts, bran, wholegrain cereals, tea and parsley.
