Pull force and air gap considerations
How air gap, geometry, and material affect magnetic pull force.
Last updated on 2026/01/26
Why air gap matters
Pull force drops quickly as air gap increases. Even small gaps can significantly reduce performance.
Key factors affecting pull force
- Magnet grade and size.
- Surface area and geometry.
- Air gap and mating material.
- Magnetization direction and pole layout.
Practical guidance
- Provide air gap and mating material in RFQs.
- Consider larger surface area before raising grade.
- Validate pull force requirements with real test conditions.
RFQ details to include
- Target pull force at a specified gap.
- Mating material and thickness.
- Required safety factors or load conditions.
