METHOD OF ACCELERATING MAGNETIC DIPOLES Russian patent published in 2012 - IPC F41B6/00 

FIELD: physics.

SUBSTANCE: in the present method, magnetic dipoles are accelerated by the field of a current pulse moving on a helical structure. Magnetic dipoles, (magnetised iron bars), having a superconducting ring winding with current inside, with diameter D_sh=20 mm and total length l_tot=65 mm, having a conical head part with length 1_cone=20 cm, are first accelerated using a gas-dynamic technique to velocity V_in=0.6 km/s, corresponding to the injection rate into the primary accelerator. A superconducting winding with outer diameter D_out=2 cm, thickness δ_sc=0.2 cm and length l_sc=40 cm is placed inside the magnetic dipoles and ring current with current density j_sc=3* 10⁵A/cm² is excited inside. The accelerated magnetic dipoles have mass m=1 kg and their flight range reaches S_max=12300 km for acceleration length L_acc=2.27 km.

EFFECT: invention increases terminal velocity of magnetic dipoles.
