Magnetization & Design

Magnetization directions: axial, radial, diametral

How magnetization direction affects performance, assembly, and supplier feasibility.

Why magnetization direction matters

Magnetization direction determines how a magnet interacts with surrounding components. It affects pull force, flux path, and assembly constraints.

Axial magnetization

  • Poles are on the flat faces of a disc or block.
  • Common for discs, blocks, and bars.
  • Often used in fixtures and simple assemblies.

Diametral magnetization

  • Poles are on opposite sides of a cylinder.
  • Common for sensors and rotating assemblies.

Radial magnetization

  • Poles are on inner and outer surfaces of a ring.
  • Used in motors, couplings, and encoder systems.

Design tips for RFQs

  • Specify the magnetization direction explicitly on drawings.
  • Include critical air gaps and mating materials.
  • Confirm whether multi-pole magnetization is required.

Supplier feasibility checks

  • Some magnetization patterns require special tooling.
  • Thin rings or small features may limit radial options.
