Summary

Researchers studied the dynamic behavior of magnetic induction in a superconducting NbTi disk with trapped flux under stepwise changes in the external magnetic field, simulating operational shocks in technical devices. The results showed a direct correlation between the stepwise changes in the magnetic field and the trapped flux response, with each increase or decrease in the field inducing a corresponding 40-50% change in trapped flux.
