Magnetic forces between two axially magnetized cylinders. Case 3: Cylinder axes are orthogonal. - QuickField simulation example
Engineering question
How to find force between perpendicular magnetized cylinders?
Engineering answer
Set up an axisymmetric QuickField DC Magnetics problem for perpendicular magnetized cylinders and evaluate force from computed field results.
Typical applications

Simulation problem
Problem TypeAxisymmetric problem of DC magnetics
Geometry
dz = 2 cm
Given
Cylinder diameter D = 1 cm,
Cylinder height H = 4 cm,
Permanent magnet relative permeability μ = 1.05,
Permanent magnet coercive force Hc = 1 000 000 A/m.
Task
Calculate the magnetic force between cylinders.
Solution
The problem geometry is 3D and we cannot directly use QuickField. But the resulting field may be decomposed into the individual fields generated by each cylinder. The free tool Cylinder PM force 3D allows the magnetic force calculation using the automatic summation of several axisymmetrical DC magnetic fields, simulated by QuickField.
