often used to analyze the magnetic flux intensity of a current system with a certain symmetry. The
useful conditions of the Ampere circuital theorem and its mathematical principles are studied. The
misunderstanding that the Ampere circuital theo- rem is incorrect in a finite-length
current-carrying straight wire system is clarified through a simple model. The uni- versality of
the Ampere circuital theorem is exemplified. It helps students to master Ampere circuital
theorem and understand the properties of magnetic fields.
