Magnetization Direction for Neodymium Magnets

Discs & Cylinders

Disc and Cylinder magnets can be axially or diametrically magnetized.  

Blocks

Block magnets are defined by three dimensions: Length, Width and Thickness.  To be consistent, we define the Thickness dimension along the axis of magnetization.  The thickness is usually the smallest dimension, but not always! We’re sometimes asked if we can provide block magnets magnetized through the length or width.  Yes, we do have some long “bar” magnets, where the magnetization is in the longest dimension. We do still define this as the Thickness, though.  

Rings

Ring magnets can be axially or diametrically magnetized.  

Spheres

Spheres can only be axially magnetized.  There is only one possible direction.  

Mounting Magnets

Round Mounting Magnets are assembled with an axially magnetized disc or ring magnet set inside a steel cup.  The north pole of the magnet faces outward. Our Rectangular Mounting Magnets are constructed in a similar fashion.
