Does a superconductor experience any forces acting upon it when it is passed through a magnetic field?

### Hornbein

Yes, as evidenced by those videos of levitating superconductors.

Adding to that, if type II superconductors would have some of the flux lines passing through the material:

Let's assume there is current flowing within the conductor will it experience a Lorentz force($F_L$)? Is it equal to($IL \times B$)?
