## Silsbee rule and other properties in superconductors

Silsbee rule: An important result of the existence of critical magnetic field is that there is also critical strength of current Ic flowing in the superconductor. Exceeding this limit also causes the disturbance of superconductivity. To derive the relation between critical current field consider a superconductor wire of radius r carrying a current I. This current will produce a magnetic field given by:

H=I/2 π r                                  (Using Ampere’s Circuital law) Continue reading “Silsbee rule and other properties in superconductors”
