<P>PROBLEM TO BE SOLVED: To provide a nuclear magnetic resonance apparatus and a magnetic field correction method that can efficiently correct a magnetic field. <P>SOLUTION: A nuclear magnetic resonance apparatus 100 is configured to spin a sample S around an axis inclined at a magic angle, and includes a correction magnetic field generation part 20 which generates a correction magnetic field, a control part 30 which controls the correction magnetic field generation part 20, and an arithmetic part 34 which uses at least one of B<SB POS="POST">Z(1)</SB>, B<SB POS="POST">1(1)</SB><SP POS="POST">e</SP>, and B<SB POS="POST">1(1)</SB><SP POS="POST">O</SP>or the linear sum of at least two of them as a primary magnetic field component of the correction magnetic field, uses at least one of B<SB POS="POST">2(2)</SB><SP POS="POST">e</SP>,, B<SB POS="POST">2(2)</SB><SP POS="POST">O</SP>, B<SB POS="POST">2(1)</SB><SP POS="POST">e</SP>, and B<SB POS="POST">2(1)</SB><SP POS="POST">O</SP>or the linear sum of at least two of them as a secondary magnetic field component of the correction magnetic field, and uses at least one of B<SB POS="POST">Z3</SB>, B<SB POS="POST">3(1)</SB><SP POS="POST">e</SP>, B<SB POS="POST">3(1)</SB><SP POS="POST">O</SP>, B<SB POS="POST">3(2)</SB><SP POS="POST">e</SP>, B<SB POS="POST">3(2)</SB><SP POS="POST">O</SP>, B<SB POS="POST">3(3)</SB><SP POS="POST">e</SP>, and B<SB POS="POST">3(3)</SB><SP POS="POST">O</SP>or the linear sum of at least two of them as a tertiary magnetic field component of the correction magnetic field. <P>COPYRIGHT: (C)2013,JPO&INPIT |
