Which outcome occurs when exceeding critical current density?

💡 Explanation

The motion of vortices initiates dissipation because exceeding critical current density leads the Lorentz force to overcome flux pinning in the Type-II superconductor. The Abrikosov vortices begin to move lowering superconductivity; therefore flux pinning initiates, generating spatially divided superconductivity, rather than an immediate destruction of it.
