the following is the description of the preferred embodiment , where the attached figures will be also explained . fig1 is a perspective view illustrating the whole appearance of the bracelet that radiates anion and far infrared rays . the bracelet ( 100 ), in accordance with the present invention that radiates anion and far infrared rays , is composed of “ c ” shaped main part ( 10 ) and a connecting arm ( 20 ). the main part ( 10 ) of the bracelet ( 100 ), in accordance with the present invention , is designed to radiate anion and far infrared rays . the main part ( 10 ) is c - shaped , and is connected to a connecting arm ( 20 ) with a clasp ( 21 ) with one end connected to hinge pin ( 25 ) so that the connecting arm ( 20 ) can rotate the main part ( 10 ) about an axle or pin ( 25 ). the other end of the main part ( 10 ) has a pin ( 26 ) connected to a clasp ( 30 ) which couples to clasp ( 21 ) to allow the bracelet ( 100 ), in accordance with the present invention , to be opened and closed . the connecting arm ( 20 ) has the clasp ( 21 ) as shown in fig4 a , 4 b , 5 . the clasp ( 21 ) defines a space ( 35 ) where magnet ( 33 ) is installed in a fixing part that holds the magnet ( 33 ). it is desirable to have a projection ( 36 ) around the magnet ( 33 ) so that when the magnet ( 33 ) couples with the magnet ( 33 ′) of the clasp ( 30 ) the projection ( 36 ) mates with the space ( 35 ) of the connector ( 30 ), and can be afixed easily . the magnets ( 33 , 33 ′) are held in place by fixing parts ( 34 ). alternatively , one of the magnets ( 33 , 33 ′) could be a ferromagnetic material . the magnets ( 33 , 33 ′) installed in the clasps ( 30 , 21 ) not only hold the connecting arm ( 20 ) in place but they also help circulate the blood due to the influence of the magnetic field when wearing the bracelet ( 100 ) in accordance with the present invention which also radiates anion and far infrared rays . when using the bracelet ( 100 ) as shown in fig2 , a user pulls up the connecting arm ( 20 ) to disengage the magnet ( 33 ) of the clasp ( 30 ), and open the bracelet , by separating the magnet ( 33 ) installed in the end of connecting arm ( 20 ) from the magnet ( 33 ′) of the clasp ( 21 ). fig6 is a schematic cross - section illustrating the material used for the bracelet ( 100 ) that radiates anion and far infrared rays . the bracelet ( 100 ) in accordance with the present invention is shown in the cross - sectional view of fig6 as including an anion radiating material layer ( 12 ) coated on the surface of a metal core ( 14 ), and a gold ( or silver ) plate layer ( 16 ) applied over the whole surface of the anion radiating material layer ( 12 ). the metal core ( 14 ) can be any appropriate metal such as upper , brass , iron , tin or alternatively it may alternatively be a polymeric material . the anion radiating material layer ( 12 ) formed on the surface of the metal core ( 14 ) is for generating anion , and comprises a rare - earth metal such lanthanum , cerium and their mixtures . in order to enhance the radiation effect of the anion and far infrared rays , it is desirable to use mineral extracted from volcanic ashes . rare - earth metals include scandium , yttrium , and the lanthanides series , i . e ., the elements with numbers 57 through 71 . the lanthanum group includes 14 elements starting from cerium . the six elements from lanthanum to samarium are called the cerium group , those from europium to lutetium also belong to the rare earth elements , however , promethium is a radioisotope , and no stable isotope exists . there are less odd - numbered elements than even - numbered ones , and generally rare - earth metals are silvery - white or gray . further , these metals oxidize slowly when exposed to air , and melt in acid and hot water , but not in alkali . these metals are very similar chemically , and usually positively trivalent compounds are made , but + 4 valent for cerium , praseodymium , and positively divalent for ytterbium , europium , and samarium . similar to alkali metal and alkali earth metal , rare - earth metals have strong positive charge , and their hydroxides are basic . fig7 is a graph illustrating the comparison between radiation strength of black body ( a ) and far infrared rays of the bracelet ( b ) that radiates anion and far infrared rays . the bracelet , in accordance with the present invention , that radiates anion and far infrared rays can be designed by making one axle longer of the connecting arm ( 20 , 21 ) than the other one , and the same result can be obtained . in order to understand better the bracelet , in accordance with the present invention the following non - limiting examples are illustrated . a molded bracelet , ( 100 ), that irradiates anion and far infrared rays was made by using for the core ( 14 ) a metal , a ceramic or a polymeric material . an anion radiating material layer ( 12 ) that irradiates significant amounts of anion is formed on the core ( 14 ) by coating anion radiating material made of minerals extracted from rare - earth metal , volcanic ashes on the surface of the core ( 14 ). next , a gold plate layer ( 16 ) was formed by coating gold film on the whole surface of the anion radiating material layer ( 12 ). in this manner , a metal material was prepared that can be used for making a bracelet that irradiates anion and far infrared rays in accordance with the present invention . by using the core ( 14 ), a c - shape main part ( 10 ) was formed , and connecting arm ( 20 ) was installed which can rotate where both ends of the main part ( 10 ) have pins to act as axles , with one end of the connector ( 20 ) combined an end of the main part ( 10 ) by the hinge pin ( 25 ). the connecting arm ( 20 ) is formed longer than the clasp ( 21 ) so that the bracelet ( 100 ) in accordance with the present invention that irradiates anion and far infrared rays can be opened / closed more easily . a clasp ( 30 ) is formed at the end of the connector ( 20 ) opposite the end connected to the main part ( 10 ). the clasp ( 30 includes a magnet ( 33 ) installed so that the clasp ( 30 ) can be connected to make clasp 21 which may also include a magnet 33 ′. the clasp ( 30 ) is composed of part ( 35 ) containing the magnet ( 33 ) and a fixing part ( 34 ) that holds the magnet ( 33 ), and a projection ( 36 ) installed around the magnet ( 33 ) so that the magnet ( 33 ) cannot be detached from the clasp ( 30 ) because it is firmly stuck to the fixing part ( 34 ). a test for a necklace made in the same manner that the bracelet was made , in accordance with the example 1 of the present invention , that irradiates anion and far infrared rays , was requested of the application & amp ; evaluation center of far infrared rays , korea institute of construction materials for measuring the amount of anion irradiation , irradiation strength and emissivity of far infrared rays . the amount of anion radiated from the bracelet in accordance with the present invention that radiates anion and far infrared rays was measured as follows . by using the device measuring charged particles , the test was done under the condition of 23 /° c ., humidity of 58 %, and the number of anions in atmosphere was 21 / cc . the number of anions irradiated from the article tested was measured and the number was calculated per unit volume , which is as follows : the far infrared rays irradiated from the bracelet in accordance with the example 1 of the present invention that irradiates anion and far infrared rays was measured compared to black body at 40 /° c ., by using ft -
