Electrical Losses and Resistance of Cryogenic Inductors with Consideration of the Effect of Magnetoresistance

摘要

A semigraphical method of calculating the electrical losses and resistance of round induction coils made of especially high purity metals (hyperconductors) - aluminum, beryllium, copper - with cryogenic cooling was developed. The peculiarity of the calculation is that it considers the effect of magnetoresistance. It uses the experimental values of the specific electrical resistance of the metals depending on the value of the induction of the transverse magnetic field at a constant low temperature. The experimental data are approximated by polynomials. (Author)
