Formula and assumptions
How this calculation works.
This uses the cross-sectional material area of a tightly wound strip. Air gaps, compression and non-uniform winding reduce the accuracy.
A worked example
Illustrative inputs only. Product properties and design dimensions are not recommendations for your project.
- Outer wound diameter
- 0.2 m
- Core diameter
- 0.1 m
- Strip thickness
- 1 mm
Approximate wound length: 23.56 m
