巧用填补法解决大学物理磁学非对称问题

摘要

Filling method is one of the effective methods for solving college physics asymmetric or non-closed problems in Magnetics. Magnetic induction, magnetic moment, Ampere force and induced electromotive force in college physics were analyzed and solved by using the filling method. Case studies show that the filling method to solve college physics asymmetric or non-closed problems in Magnetics can avoid complex mathematical integration and facilitate the solution of the problems. Using filling method to solve practical problems in teaching, not only the teaching effectiveness can be more effective, but also the abilities of logical thinking and solving practical problems can be cultivated.%　　填补法是求解大学物理磁学非对称或非闭合问题的有效方法之一。本文利用填补法对大学物理磁学中的磁感应强度、磁力矩、安培力和感应电动势进行了分析与求解。实例分析表明，利用填补法求解大学物理磁学非对称或非闭合问题时可避免复杂的数学积分，便于问题的求解。教学中引入填补法解决实际问题，不仅可使教学效果事半功倍，还可培养学生的逻辑思维能力和解决实际问题的能力。
