Abstract
Provided are a magnetic field device that can efficiently drive molten metal with a large driving force, and a method of driving molten metal using the magnetic field device. A magnetic field device 1 according to an embodiment includes a rotating body 2 to be driven to rotate around a central axis, a magnet 3 fixed on the rotating body 2 and having an upper surface magnetized to N pole, and a magnet 4 fixed on the rotating body 2 and having an upper surface magnetized to S pole, the magnet 3 and the magnet 4 being arranged opposite each other to form a groove G that is longer in length than in width.

A magnetic field device comprising:
- a rotating body to be driven to rotate around a central axis;
- a first magnet fixed on the rotating body and having an upper surface magnetized to N pole;
- and
- a second magnet fixed on the rotating body and having an upper surface magnetized to S pole,
- the first magnet and the second magnet being arranged opposite each other to form a groove that is longer in length than in width,
- wherein the first magnet and the second magnet rotate together with the rotating body as the rotating body rotates, thereby causing a time variation of magnetic flux that penetrates molten metal so as to drive the molten metal.
