Calculation of open magnets according to own specifications
Important information
Table for open magnets in Nd /SmCo / HF, but not for AINiCo. Magnetized through thickness / axial.
Holding force calculated theoretically; without coating (10 … 50 μ).
For precise calculation, please use professional tools.
