Definition for PO-LAR'I-TY
PO'LAR-I-SCOPEPO-LAR-I-ZA'TION
PO-LAR'I-TY, n.
That quality of a body in virtue of which peculiar properties reside in certain points; usually, as in electrified or magnetized bodies, properties of attraction Or repulsion, or the power of taking a certain direction. Thus we speak of the polarity of the magnet or magnetic needle, whose pole is not always that of the earth, but a point somewhat easterly or westerly; and the deviation of the needle from a north and south line is called its variation. A mineral is said to possess polarity, when it attracts one pole of a magnetic needle and repels the other.
