Magnetization direction
Two magnets with the same size and material can behave very differently if the magnetization direction is different. If the part goes into an assembly, fixture, motor, sensor, or closure, this detail matters early.
Axial magnetization is common for discs and cylinders. Thickness magnetization is common for blocks. Diametral magnetization, multipole magnetization, and custom pole patterns need clearer drawings or samples.
If you are unsure, send the drawing, product photo, or the way the magnet will touch another part.
Some magnetization directions are standard. Others need different tooling, inspection, or production steps. That can affect MOQ, cost, and lead time.
Common directions
Simple words and a marked drawing are usually enough for the first check.
| Direction | Common shape | What to send |
|---|---|---|
| Axial | Disc, cylinder, ring | North and south poles on the two flat faces. |
| Thickness | Block, square, rectangle | Poles on the two large flat faces or another specified face pair. |
| Diametral | Disc, cylinder, ring | Poles across the diameter; send a sketch if possible. |
| Multipole or custom | Motor parts, sensor parts, special assemblies | Drawing, pole count, pole layout, and sample if available. |
Quote checklist
The goal is to avoid guessing the pole direction.
Magnetization FAQ
These are the questions that usually slow down a magnet quote.
The magnet is magnetized through its flat faces. It is common for many discs, cylinders, and rings.
The poles are across the diameter, not through the flat faces. It should be shown on a drawing or confirmed by sample.
Custom magnetization can be reviewed. The quote depends on material, shape, pole layout, quantity, and tooling needs.
Send the product photo, assembly drawing, or old sample. We can ask the right follow-up questions before quoting.
Yes. Size, grade, contact surface, and pole direction all affect the final force result.
