This figure shows the cross-section <strong>of</strong> the Tin tube. We are<br />
interested in the flux through the hollow.<br />
When this is superconducting, current is only possible very near<br />
the surfaces A and B, within the penetration depth. Further in<br />
the bulk, there is no current because there is no field, since all<br />
field is expelled.<br />
