1. A method for forming a workpiece by a magnetic field including the steps of:
- producing a high current impulse;
producing said magnetic field by applying said high current impulse through a high current loop circuit located in its entirety outside said workpiece, whereby said magnetic field exerts a force on an electrically conducting object selected from the group comprised of workpiece compression rings and workpieces;
beginning said high current impulse in the form of a half sine wave defined by the equation (ω
t=0 . . . π
); and
reducing the cycle of said high current impulse to cause it to fade away as defined by the equation (ω
t>
π
. . . ∞
).

Abstract
A method for forming and joining workpieces by a magnetic field produced by a current impulse applied through a high current loop, whereby the magnetic field exerts a force from outside on an electrically conducting workpiece or on electrically conducting compression rings encircling the workpiece, wherein the current impulse begins in the form of a half sine wave defined by the equation (ωt=0 . . . π); and then fades away as defined by the equation (ωt>π . . . ∞).
