Application Evaluation Matrix

Evaluation Metric	Typical Range	Buyer Relevance
Braking Force	Scalable by magnet area, conductor design, speed, and gap	Defines the expected stopping power without physical contact under the target speed curve.
Force Versus Speed Curve	Application-specific	Eddy current braking is speed dependent, so a single force value can be misleading.
Conductor Temperature Rise	Defined by energy per stop and duty cycle	Heat in the conductor can become the limiting factor even when magnets remain stable.

Risk and Mitigation

Thermal demagnetization: High-temperature NdFeB or SmCo magnets.
Overstated low-speed stopping force: Evaluate braking force across the full speed curve and include mechanical stopping strategy if needed.
Conductor overheating during repeated stops: Define duty cycle, cooling path, conductor material, and temperature limit before magnetic layout freeze.

Validation Deliverables

Field profile at the specified working gap.
Critical dimension and mounting datum inspection.
Grade, coating, and temperature-rating documentation.
Packaging notes for strong magnetic modules.
