✦ Synopsis

A method which measures directly transvere resistivity in multifilamentary superconducting composites has been developed. Measurements of the composites having filaments of Nb Ti-50 alloy (Nb -50% weight Ti) embedded in a copper matrix have been carried out at 4.2 K, 12 K, and 300 K in a field of up to 6 T. Using the obtained values of the effective transverse resistivity pΒ±, the calculation of the eddy current losses has been performed. These losses are compared with the experimental values measured by a calorimetric method.

For the current distribution inside a multifilamentary superconducting wire carring a dc transport current in a rapidly changing transverse magnetic field, inconsistencies with the existing models are shown by the following experimental evidence: when a transverse magnetic field is applied, the dist
