Method of making non-rectangular magnets

A method comprising:

• providing a first powder comprising iron;
• magnetically aligning the first powder;
• compacting the first powder into a compacted powder product having a non-planar surface having an arcuate shape, wherein the compacting comprises dynamic magnetic compaction;
• increasing the magnetic coercivity of at least one of the first powder or the compacted powder product by adding a material comprising Dy to at least one of the first powder or the compacted powder product by diffusing Dy into the compacted powder product and further comprising heat treating the compacted powder product;
• and wherein the non-planar surface has an arcuate shape, and wherein the compacting further comprises providing a mold having a recess defined therein by an arcuate shaped surface and opposed side walls, a first die tool in a ring, the first die tool having a planar shaped face, wherein the mold is positioned under the ring and wherein the first powder is positioned in the ring against the planar shaped face of the first tool die and so that the powder includes a raised portion in the recess in the mold, and wherein the compacting causes the ring to collapse and the powder to be compacted against the planar shaped face of the first tool die.
