METHOD FOR PRODUCING RUNNING MAGNETIC WAVE AND DEVICE FOR REALIZATION OF METHOD Russian patent published in 2005 - IPC

FIELD: electric engineering.

SUBSTANCE: super-conductive rod is magnetized to field with value within limits of thermal-magnetic non-stability of super-conductive state of rod to produce higher speed of spreading for running magnetic wave with amplitude greater than 1 Tesla. Collinearly to direction of magnetic field rod is placed, in super-conductive state, magnetic field is formed with value, limited by thermo-magnetic non-stability area, and then one of rod portions is switched to normal state. Device for realization of method has primary winding, forming magnetic field and connected to current power source. Inside the primary winding along direction of magnetic field rod is placed in super-conductive state. On one of rod portions additional winding is positioned, connected to pulse current source. Area of thermal-magnetic non-stability is characterized by magnetic field of value B, lower value B₁ of which is determined from expression where T_c - critical temperature of super-conductive rod, T_b - coolant boiling temperature, C(T) - heat capacity of ultra-conductive rod material, upper limit B₂ of which is reached, when difference of magnetic field inside and outside of ultra-conductive rod becomes less than B₁.

EFFECT: spreading of constant magnetic field along spreading axis, with increased values of amplitude and spreading speed of running magnetic wave.
