  We develop protocols to confine charged particles using time-varying magnetic
fields and demonstrate the possible non-torus configuration resulting from the
distribution of single-particle motion orbits. A two-step strategy is proposed
to achieve this goal: preliminary protocols are contrived by solely considering
the magnetic force; afterwards they are evaluated and selected through
numerical solutions to the equation of motion, taking into account inductive
electric fields. It is shown that a fine-tuned tangent-pulse protocol can
maintain its centralized configuration even in the presence of associated
electric fields, which illuminates an alternative approach to designing the
confinement scenario for fusion plasmas.
