Abstract
A projectile for use in an electromagnetic projectile launcher is provided with a conductive open loop which is mechanically attached to the body of the projectile. Means are provided for electrically connecting the open loop between a pair of generally parallel projectile launching rails when the open loop is in a predetermined angular orientation with respect to the rails. Current flowing in the loop then interacts with magnetic flux produced by current flowing within the rails to place a torque on the loop which can be used to spin-stabilize the projectile or to prevent rotation of the projectile depending upon the particular application.
