Measuring magnetic field.<br />
This graph shows the magnetisation <strong>of</strong> lead in liquid helium,<br />
plotted against the applied field.<br />
Livingston, Physical Review, vol. 129 (1963), p. 1943<br />
Below a certain critical field, the magnetisation is equal and<br />
opposite to the applied field. So the resultant field inside the<br />
superconductor is zero.<br />
