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.
