A magnetic attraction preventive system includes an approach detection unit which generates an approach detection magnetic field and detects the approach of a magnetic material to a magnetic resonance imaging apparatus on the basis of a variation in the strength of the approach detection magnetic field, and a preventive unit which prevents magnetic attraction of the magnetic material to the magnetic resonance imaging apparatus when the approach detection unit detects the approach of the magnetic material to the magnetic resonance imaging apparatus.
