What are the Directions of Magnetization?
It is the first step to achieving permanent magnet magnetism such as SmCo, NdFeB, and more. The magnetization directions represent the magnetic assembly’s south and north poles. A permanent magnet’s magnetic properties are derived from its crystal structure that is easily magnetized. The deconstruction makes the magnet possess excellent magnetic properties when exposed to the strong external magnetic field.
Cylinder/Disc/Rod
-
Axially Magnetized- Magnetized through thickness or length
- Flat faces are the strongest points
-
Diametrically Magnetized- Magnetized through its diameter
- Curved surface are the strongest points
-
Radially Magnetized- North and south magnetization
- Not practical for magnetization machine tooling cost
Blocks/Cubes/Rectangles
-
Through Thickness- Rectangle’s smallest direction is the thickness
- The end of the thickness is the strongest points
- Magnetized through thickness
-
Through Width- Second largest rectangle dimension is the width
- The end of the width is the strongest point
- Magnetized through the width
-
Through Length- Largest rectangle dimension is the length
- The end of the length is the strongest points
- Magnetized through the length
Arcs and Segments
-
Diametrically Magnetized Arc- The curved surfaces are the strongest points
- Magnetized from outside and inside Radius
-
Chord Magnetized Arc- The flat angled surfaces are the strongest points
- Magnetized across the arc
-
Axially Magnetized Arc- The flat faces are the strongest points
- Magnetized through thickness
Pot or Cup Magnets / Sphere Magnets
-
Axially Magnetized Pot/Cup MagnetsA pot or cup magnets are enclosed in a stainless steel sheet. The shell absorbs magnetic field on one side while forcing it in the opposite direction. Therefore, a double pull is formed at the magnet’s end.
-
Axially Magnetized Sphere Magnets- Opposite ends are the strongest points
- Magnetized through diameter
Magnets’ Orientation Direction
