Yes, vortices in Type II superconductors can move. In fact, their ability to move is what makes them useful for practical applications.
Vortices in Type II superconductors move due to the interaction between the magnetic field and the supercurrent flowing through the material. This interaction creates a force on the vortices, causing them to move.
The movement of vortices in Type II superconductors is influenced by several factors, including the strength of the magnetic field, the temperature of the material, and the material's critical current density.
No, vortices in Type II superconductors do not typically move in a straight line. They tend to move in curved paths, following the path of least resistance within the material.
The movement of vortices in Type II superconductors can be unpredictable, as it depends on a complex interplay between various factors. However, scientists have developed models and simulations to better understand and predict the movement of vortices in these materials.
