ABSTRACT
A long superconducting cylinder of radius r0 is placed in a solenoid of radius r1 > r0 (Fig. 2-1). Experimental geometry to measure the critical field. The sample is a long cylinder (of length L and radius r<sub>0</sub>). It is placed in a coil of radius r<sub>1</sub>. https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9780429497032/d2b0510a-8f84-4d3a-8776-dff0770e5b14/content/fig2_1.tif"/>
