Abstract
A method of increasing volume ratio of magnetic particles in a MnBi alloy includes depositing a MnBi alloy powder containing magnetic particles and non-magnetic particles on a sloped surface having a magnetic field acted thereupon. The method further includes collecting falling non-magnetic particles while separated magnetic particles are magnetically retained on the sloped surface.
