Abstract
PURPOSE: To obtain easily the magnetic field gradient of a desired size by using a nonmagnetic casing having a probe.
CONSTITUTION: A cylindrical nonmagnetic casing 5 is prepared, which is consisting of flange parts 5a at a front and a rear parts, a taper part provided with a coil positioning groove 5c from both side surfaces 5b to a flange parts 5a, a measuring sample inserting port 5d formed at an upper part, and a maintaining equipment 6 threaded accessibly to the respective side face of the flange parts 5a. After at a center, a spacing part 7' communicating with an insertion port 5d is formed, and a probe 7 having an oscillation and receiving coils at circumferential edge of the spacing 7' is inserted and fixed into the casing 5, two coils 8 are wound to the groove 5c and the casing 5 is fixed between the magnetic electrodes 1 and 2 of the electromagnet so as to locate a center of the spacing 7' at an opposing center between both magnetic pole surfaces 1' and 2'. Thus, when the sample to be measured is inserted into the spacing 7', the center is easily coincided with the center of the imaginary rectangular shape formed by four linear conductive portions 8' as a pair of the two coils 8 in accordance with the accuracy in case the groove 5c is formed.
