<p>PROBLEM TO BE SOLVED: To provide a magnetic field generation apparatus that generates a desired magnetic field.SOLUTION: For generating a desired magnetic field, a magnetic field generation apparatus 1 includes: an inner coil pair 10 arranged such that coil axes are the same; an outer coil pair 20 arranged such that coil axes are the same outside of the inner coil pair 10; bipolar power supplies 31-34 for applying AC currents to the inner and outer coil pairs 10, 20; changers 60 capable of changing a coil position of each of the inner and outer coil pairs 10, 20 as keeping the coil axes the same; and a control section 50 for controlling the bipolar power supplies 31-34 to apply AC currents to the inner and outer coil pairs 10, 20 within a magnetic field region.</p> |
