7D40.20 - NMR - Air Bearing

Code Number:
7D40.20
Demo Title:
NMR - Air Bearing
Condition:
Excellent
Principle:
Magnetic Resonance
Area of Study:
Modern Physics
Equipment:
Teach Spin Apparatus, Standard ball with stem, Special ball without stem, magnetic accessories.
Procedure:

Place the ball with the stem into the apparatus and turn on the magnetic field.  Precession due to applied magnetic field can also be shown if the ball is spun carefully about a central axis.
