磁力教學實驗裝置

• 通過磁力措施磁矩
• 措施分貝/ DZ與z為一個電流回路
• 解析普適E＆M誤解

MF1-A是一個動手的儀器，旨在探索部隊由外部磁場的**磁偶極子。基本上所有的入門文本討論磁偶極子的力量，但學生還沒有機會進行定性或定量的實驗，這種相互作用。

MF1-A使用一個小的釹-鐵-硼**磁化的磁盤作為一個模型系統對于一個理想的偶極矩，以及一對Helmholtz線圈創建的外部磁場。使用MF1-A的各種實驗都適合高中和大學的學生。我們豐富的經驗將證明 磁力矩 M T 1-A，我們相信，磁力實驗不僅將驚喜（甚至驚奇）大多數學生，但也將有助于清除上*普遍的物理誤解E＆M 我們已經開發了這個經濟實惠的設備，給學生具體的學習經驗與磁力。

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.
