3. Earth's Field w/ Gradient/Field Coil EFNMR 1-B
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
Helmholtz Coils:
• Permit Absolute Measurement of Nuclear Magnetic Moments
• Provide Fields for Experiments on 31P and 2H Nuclei
• Show Quantitatively that Magnetic Fields Add as Vectors
