Preparation and Characteristics of Cloth Inductor
A cloth inductor consisting of mechanically interwoven amorphous ferromagnetic fibers and conducting fibers is described, and the inductor characteristics reported for various fiber lengths, diameters, and weaving patterns. The inductance L increases nearly in proportion to the fiber length, and in proportion to the second power of the amorphous fiber diameter and the second power of the number of conducting fiber turns per unit length, as expected. The leakage flux and total inductance also depend on the relative flux orientations of neighboring amorphous fibers.
Structure and characteristics of wire inductor.
The miniaturization of magnetic cores wound by copper wire is difficult because of the structure. In this paper the authors describe a miniaturized inductor containing amorphous magnetic wire which they have succeeded in realizing with a large inductance per unit volume. Further, the size of the inductor is smaller than that of inductors with conventional cores. The frequency characteristics of inductance of the wire inductor is controlled by the demagnetizing factor of the amorphous wire, and one thus can realize an inductor which operates in sub-MHz frequency domain.
The effect of continuous exposure to low frequency electric fields on three generations of mice: A pilot study
Mice were allowed to mate, gestate, deliver and rear their offspring for 3 successive generations while being continuously exposed to 60 Hz electric fields. Mice exposed to vertical electric fields exhibited decreased body weights at 35 days postpartum and increased mortality, rates for 3 successive generations. Mice exposed to horizontal electric fields exhibited decreased body weights for 2 successive generations.
