The diagram shows an idealization of the "floating magnet trick" of Figure 10.50. Before it is cooled, the superconducting disk on the bottom supports the small permanent magnet simply by contact. After cooling, the magnet floats. Make a sketch, showing what newmagnetic fields arse. Where are the currents that produce them?

Magnetic field of a superconductor.

A vector field that describes the magnetic influence of the electric charges in relative motion and due to some magnetic material is called magnetic field.

The superconductors have the properties of a magnet.

The sketch for arise of new magnetic field lines of super conductor material is shown below.

Figure 1

The new magnetic field lines are arise because the magnetic field lines generated by the surface current of the superconductor will cancel out the magnetic field inside the super conductor such that there is not magnetic field inside the super conductor.

Therefore, the sketch for arise of new magnetic field lines is shown in figure 1.
