Common magnetization patterns
Axial magnetization is common for discs, rings, and blocks where the field travels through thickness. Diametric magnetization is often used for rotating sensor targets and small cylinders. Radial and multi-pole patterns are common in motor, encoder, and array applications where pole count and field shape matter.
Fixture and material limits
Custom magnetization can require dedicated tooling, field strength, and fixture validation. Bonded and injection molded magnets can support complex pole patterns, while sintered magnets may provide higher energy density but require more attention to geometry and fixture feasibility.
Specify the measurable output
The quote package should define the pattern, pole count, orientation, test location, acceptable flux range, and measurement method. A clear inspection setup helps avoid disputes between surface gauss readings, open flux readings, and application-level sensor or torque results.
