磁力矩教學(xué)實(shí)驗(yàn)裝置

磁矩與磁場相互作用

• 測量磁矩四個(gè)獨(dú)立的方法
  • 靜轉(zhuǎn)矩
  • 諧波振蕩
  • 歲差
  • 磁力
• 旋磁比
• “磁共振”自旋反轉(zhuǎn)模擬

磁力矩為學(xué)生提供一個(gè)機(jī)會，不僅使定量測量，電磁力，扭矩和簡諧運(yùn)動， 而且要研究，定量，歲差現(xiàn)象。

本儀器是同樣在主場榮譽(yù)大一實(shí)驗(yàn)室，大二中級/初級物理實(shí)驗(yàn)室，核磁共振，在任何一個(gè)現(xiàn)代物理學(xué)或先進(jìn)的實(shí)驗(yàn)室高級模擬。

雖然每介紹物理教材討論一個(gè)電流回路與磁場，磁力矩和磁力的相互作用是**能夠證明這種互動的教學(xué)儀器。

• 使用小型磁化磁盤，像磁偶極子的行為，衡量學(xué)生的現(xiàn)象，從磁力矩或磁力。
• 學(xué)生可以判斷磁盤的偶極矩在各種方式使用基本的E＆M和力學(xué)原理。
• 此外，M 噸 1-A可以用來證明基本原則包括脈沖核磁共振自旋翻轉(zhuǎn)磁共振。

Introduction

Magnetic Moments Interacting with Magnetic Fields

• Measure Magnetic Moment Four Independent Ways
  • Static Torque
  • Harmonic Oscillation
  • Precession
  • Magnetic Force
• Gyromagnetic Ratio
• "Magnetic Resonance" Spin-Flip Analog

Magnetic Torque offers students an opportunity not only to make quantitative measurements involving electromagnetism， torque and simple harmonic motion but also to study， quantitatively， the phenomenon of precession.

This instrument is equally at home in an Honors Freshman Lab， an Intermediate Sophomore/Junior physics laboratory and， as an analog for Nuclear Magnetic Resonance， in either a Modern Physics or Advanced Senior Laboratory.

Although every introductory physics textbook discusses the interactions of a current loop with magnetic fields， Magnetic Torque and Magnetic Force are the only teaching apparatus capable of demonstrating such interactions.

• Using small magnetized disks that act like magnetic dipoles， students measure phenomena that result from magnetic torque or magnetic force.
• Students can determine the dipole moment of the disk in a variety of ways using fundamental E&M and mechanics principles.
• In addition， Mt1-A can be used to demonstrate basic principles of magnetic resonance including a Pulsed NMR spin-flip.
