Optimization of Dimensions of a Device for Circular Magnetization of Cylindrical Components. V. Circular Field Component in One Sector of Toroidal Coil

Analytical expressions for calculating the distribution of the circular magnetic field component generated by a coil shaped as a toroid sector have been obtained. The field distribution has been analyzed for different parameters of a toroidal coil divided into sectors. The maximal circular component of magnetic field is generated in a limited region in space by a coil composed of different sectors containing turns wound in several layers on top of one another. The field intensity depends on the sectorial angle, its inside and outside radius, and the number of layers in the winding. The sectorial angle corresponding to the maximal circular component depends on the radius-vector of the observation point.
