Introduction

Gradient Coils:

• Homogenize Local Earth's Magnetic Field
• Permit Measurement of Spin-Spin Relaxation (T₂)
• Demonstrate One-Dimensional NMR Imaging (MRI)
• Generate Observable (and Audible) Spin-Echoes

• Permit Absolute Measurement of Nuclear Magnetic Moments
• Provide Fields for Experiments on³¹P and²H Nuclei
• Show Quantitatively that Magnetic Fields Add as Vectors

The Gradient/Field Coil System was initially developed by Professor David Van Baak of Calvin College to be used with his TeachSpin EFNMR1-A. Once we saw it in action� we knew we had to make it universally available. Collaborating with Dr. Van Baak� we have created a robust apparatus that can be used on many levels. Dr. Van Baak has written the detailed instruction manual for both the instructor and the students. We believe that the Earth's Field NMR� with this coil system� is without doubt� the best instrument for students beginning their study of magnetic resonance. It has no equal!
