Maxwell denkleminin AV formülasyonu esas alınarak, zamana bağlı bir akım altında süperiletken telin elektromanyetik özelliklerini çözmek için yeni bir sayısal model geliştirilmiştir. Farklı akım genlikleri için alternatif akım (AA) kayıpları hesaplanmış ve iki boyutlu (2B) H formülasyonu ile kıyaslanarak modeller arasında oldukça iyi bir uyum sağlanmıştır. Önerilen model, hesaplama süresini mevcut modellere kıyasla önemli ölçüde azaltmaktadır. 3B'deki akım ve manyetik alan dağılımları, geçen akımın farklı zaman adımları için gösterilmiştir.
