Title:

Calculation of Magnetic Field of Helical Coils

Date of publication:

Feb. 1990

Key words:

helical coils, numerical calculation, magnetic field

Abstract:

Formulae of magnetic field calculation of finite size helical coils with rectangular cross section [ Kakuyugo Kenkyu 57 (1988) 318 ] are extended to the case that the size of the coil, or the relative position to the guiding curve, varies along the arc length of the guiding curve. The error caused by the inappropriate formulae or inappropriate current model is discussed.
