Repelling of the block magnets
QuickField simulation example
Two rectangular prism shaped permanent magnets repel one another.
Problem Type
Plane-parallel problem of magnetostatics
Geometry
w=1.5" (38.1 mm) - magnet width;
t=0.25" (6.35 mm) - magnet thickness;
L=0.25" (6.35 mm) - magnet length;
δ=0.5" (12.7 mm) - gap between the magnets.
Task
Calculate the repelling force between two magnets.
Solution
To calculate the correct result an integration contour is drawn in the air around one of the magnets.
Result
| Repelling force | |
| QuickField | 3.30 N |
|---|---|
| Reference* | 3.50 N (0.77 lb, 1 lb = 4.54 N) |
