| 摘要 |
The present invention relates to a launching device using a rotary magnetic material, comprising: an acceleration tube of which the inside is empty and which is a tube made of a nonmagnetic material twined in a spiral shape to be safe and work with low-power; a stator which forms an electric field when a plurality of coils wound around the outer side of the acceleration tube become magnetized when an electric current is applied thereon; and a magnetic material which receives force from the electric field to be rotated along the acceleration tube and launched to the outside. |
