摘要
磁偶极子与电偶极子一样,都是非常实用的物理模型。在现行少课时教改的趋势下,让同学尽早认识磁偶极子是一桩非常有意义的事。教材中对磁偶极子虽有论述,但用到的数学既较深奥,也有点繁琐,直接导致初学者在认识上产生障碍。在教学中,磁偶极子与磁场的相互作用力运用培安力公式来计算,方法直观易懂,学生较易接受。
Magnetic dipole, together with electric dipole, is a pretty practical physical model. It is of significance for college students to understand magnetic dipole under present trend with less class hours. However, the magnetic dipole discussed in the textbook involves deep maths application and is a little fussy, which makes beginners have obstacles. In teaching, Ampere force is used to count the mutual force of magnetic dipole and magnetic field and the method is visual and easy to understand and take in.
