        Neodymium is a class of Rare Earth material. These magnets are the most powerful class of magnet material commercially available today.

        Neodymium magnets are graded according to the magnetic flux output per unit volume. Higher values indicate stronger magnets and range from N35 up to N52.

        I do not know much about magnets and could not tell you about 700m magnet
