  • Comparison of magnetic effects was conducted between static, pulse, and alternating magnetic field applications.
  • Time to reach maximum magnetic effect and dependence on field frequency were analyzed.

    • Main Results:

    • Pulse and alternating magnetic fields significantly reduce the time required to achieve maximum magnetic effect compared to static fields.
    • The observed magnetic effects demonstrate a clear dependence on the frequency of the applied magnetic field.
    • Pulse and alternating magnetic fields were found to increase the stability of quasi-stable structures more effectively than static fields.

    Conclusions:

    • Dynamic magnetic fields (pulse and alternating) offer faster and more effective magnetic manipulation than static fields.
    • Magnetic field frequency is a critical parameter influencing magnetic effects.
    • The enhanced stability of quasi-stable structures by dynamic fields has implications for materials processing and applications.
