Abstract
The present invention is aimed at providing a sintered magnet production system that can prevent the influences of a leaking magnetic field in an orienting process. A sintered magnet production system according to the present invention has a filling meansfor filling an alloy powder into a filling/sintering container, a sintering meansfor sintering the alloy powder, and an orienting meanswith an air-core coil for producing a magnetic field for orienting the alloy powder in the filling/sintering container after the filling process and before the sintering process, the axis of the air-core coil being displaced from a straight line connecting the filling meansand the sintering means. The magnetic field leaking from the orienting meansis strongest on the extended line of the axis of the air-core coil and relatively weak in the direction perpendicular to the extended line. By displacing the axis of the air-core coil from the aforementioned straight line, the magnetic field leaking from the orienting meansis weakened at the positions of the filling meansand the sintering means, so that a magnet with high characteristics can be obtained.
