Udrişte, C.; Udrişte, A.; Balan, V.; Postolache, M. Magnetic dynamical systems. (English) Zbl 0860.35132 An. Științ. Univ. Al. I. Cuza Iași, Ser. Nouă, Inf. 4, 105-126 (1995). Summary: After describing elementary notions of phase portrait theory and basic plane configurations, the critical elements for a magnetic field generated by different configurations of piecewise rectilinear circuits wandered by currents are studied. The associated magnetic field, the corresponding scalar and vector potentials, and the description of critical point sets, are presented as well.
