Abstract

PURPOSE:To obtain a large output voltage by convering magnetic flux only on a magnetic gap. CONSTITUTION:When magnetic flux flows from magnet 10 to yokes 11 and 12 and pole pieces 14 and 15, pieces 14 and 15 are given fixed polarity and magnetic flux flowing into the top part of piece 15 is absorbed by holder 13 composed of a magnet. Therefore, the magnetic flux density of ring-shape opposing parts (a) of pieces 14 and 15 increases, so that a difference in magnetic flux density between gap 16 and internal circumference part (b) will be extremely large. Then, a large output voltage can be obtained by positioning the external circumference part of a printed coil at this opposing part (a).
