Evolution of free‐boundaries conduction into a superconductor sphere in magnetic variable field

Abstract

Purpose

Presents a study of a bulk superconductor sphere placed in a uniform magnetic induction field b₀(t).

Design/methodology/approach

Adapts some macroscopic laws for the numerical simulation of its evolution. This evolution is determinated by the front tracking method (FTM).

Findings

The deduction of some consequences concerning hysteresis losses, and comparison to a direct method are done.

Originality/value

Helps to solve some complex three‐dimensional eddy current problems in industrial devices.
