Nuclear Magnetic Resonance (NMR)

Since current in each winding of symmetrical coil is opposed to the other wouldn't the magnetic field tend to cancel each other out? Current flows one direction then loops back on itself so therefore I would think they would cancel each other.

Asking out of curiosity since I've never seen that configuration.

Sir
Fellows are very busy ATM
However I will be certain your question is noticed


Thank you for the interest and question.

Hi Kajunbee,

These are not solenoidal coils, they are flat pancake coils.  We don't use the axial field that passes through the coils, we use the radial field that passes over the flat surface of the coils.  In the bucking configuration the axial fields from each coil do indeed oppose each other, but the radial fields between the two coils are additive.
