MF1-A是一个动手的仪器,旨在探索部队由外部磁场的永久磁偶极子。基本上所有的入门文本讨论磁偶极子的力量,但学生还没有机会进行定性或定量的实验,这种相互作用。
MF1-A使用一个小的钕-铁-硼永久磁化的磁盘作为一个模型系统对于一个理想的偶极矩,以及一对Helmholtz线圈创建的外部磁场。使用MF1-A的各种实验都适合高中和大学的学生。我们丰富的经验将证明 磁力矩 M T 1-A,我们相信,磁力实验不仅将惊喜(甚至惊奇)大多数学生,但也将有助于清除上最普遍的物理误解E&M 我们已经开发了这个经济实惠的设备,给学生具体的学习经验与磁力。 Introduction
Measures Magnetic Moment by Magnetic Force
Measures dB/dz vs z for a Current Loop
Resolves Pervasive E&M Misconceptions
MF1-A is a hands-on instrument designed to explore the forces on a permanent magnetic dipole by external magnetic fields. Essentially all introductory texts discuss magnetic forces on dipoles, yet students have not had an opportunity to perform either qualitative or quantitative experiments with this interaction.
The MF1-A uses a small neodymium-iron-boron permanently magnetized disk as a model system for an ideal dipole moment, and a pair of Helmholtz coils to create the external magnetic fields. The various experiments using MF1-A are appropriate for both high school and university students. From our extensive experince demonstratingMagnetic Torque Mt1-A, we are convinced that Magnetic Force experiments will not only surprise (even amaze) most students, but will also serve to clear up on the most pervasive physics misconceptions in E&M. We have developed this affordable apparatus to give students concrete learning experiences with magnetic forces.
