Abstract:
1. An apparatus for nuclear magnetic resonance examination of a thin sample in a static magnetic field, comprising at least one coil comprising at least one wire path adapted to carry a controllable electric current and routed to define a plurality of continuous figure eight double loops, wherein: each loop in each double loop comprises an array wire element and a return wire portion; the array wire elements in each loop are disposed substantially coplanar and substantially parallel; the plurality of double loops are arranged so that the current in all the array wire elements flows in the same coordinate direction whereby the array wire elements define a coil array for generating a magnetic field, substantially uniform in direction and strength, generally parallel to an imaginary plane containing the coil array; and when the sample is oriented so that the static field is normal to a plane of the sample, the at least one coil is disposable parallel to a plane of the sample so that the direction of the magnetic field generated by the coil is substantially perpendicular to the static field.
