The Bloch-NMR diagnostic tool has shown good efficiency not only analyzing biological and
physiological properties of living tissues. The Bloch-NMR has been used in this research work to
analyze the penetration depths of superconducting material and thin film. From the two well
known London penetration depths, various relationships between the penetration depth and other
superconducting quantities were derived (which are theoretically and experimentally valid). The
major objective is to explore new ways penetration depths can be measured. A new
superconducting quantity (penetration velocity) was discussed - whose relationship with other
superconducting quantities were worked out for further researc
