The Calculation of the Mutual Inductance of Circular Filaments in Any Desired Positions

摘要: The calculation of the mutual inductance circular coils whose cross-sectional dimensions are small, compared with their distance apart, depends upon basic formulas for filaments. case coaxial filaments has been quite thoroughly treated and any desired accuracy is attainable. However, available more general cases such as circles parallel or inclined axes slowly convergent considerable ranges parameters admit only rough accuracy. present paper concerned providing tables capable giving a moderate accuracy, amount labor, even in complicated cases. apply to calculations equal axes, nearly radii having which intersect at center one circles. This latter enters design variometer composed two small cross sections; former applicable eccentric axes. A formula derived, allows fairly simple method computation case, by employment chart flux distribution about filament carrying current. An few parts thousand readily
