CREATION METHOD OF VORTICAL MAGNETIC FIELD Russian patent published in 2009 - IPC H01F7/00 H02N11/00 

FIELD: physics.

SUBSTANCE: invention concerns magnetism physics, to obtaining of the unidirectional pulsing vortical magnetic field creating a magnetic field pulling on a circle in relation to an iron-core body to moving in it. The creation method of a vortical magnetic field along some circle, equivalent to magnetic field rotation, consists that some constant magnets are symmetrically located concerning a circle. Longitudinal magnetic axes of constant magnets are combined with tangents to the specified circle in the points symmetrized on this circle. The number n constant magnets is defined from a condition: 2π/n ≤ ΔΘ, where angle ΔΘ=arccos[1/(1+γ)], parametre γ=d/R, and d - distance from cross points of longitudinal magnetic axes of constant magnets with their planes of poles to the specified circle of radius R. Force function of constant magnets D and the parametre are chosen in a such manner, that the retarding moment created by the previous magnet, partially or it was completely compensated by the accelerating moment of the subsequent magnet in a direction of a vortical magnetic field. Value D=µ₀µνS²H₀ ²/8π²R⁵, where µ₀=1,256·10^-6 H/m - absolute magnetic permittivity of vacuum, µ relative permeability of an iron-core body in volume ν that interacts with the magnetic field which intensity is equal H₀ in a plane of poles of constant magnets with a cross section of their poles S.

EFFECT: reception of rotary movement of an iron-core body, that is in reception of mechanical (electric) energy from static magneto-periodic structure.
