American Association of Physics Teachers, Summer meeting 2012
In our modern physics laboratory sequence, we use “Tracks” in which the
students perform a series of related investigations that build on each other.
Typically a track has at least one investigation that is a mechanical analog
of a modern physics investigation. One of those tracks is Nuclear Magnetic
Resonance (NMR). The apparatus in this investigation is typically a black
box system in which it is difficult to visualize what is physically happening.
Using a spherical Neodymium magnet in an air-bearing and two sets
of Helmholtz coils to provide guide and excitation fields we are able to
mechanically simulate NMR.
