Magnetic forces between two axially magnetized cylinders. Case 2: Cylinder axes are parallel

QuickField simulation example

Problem Type
Axisymmetric problem of DC magnetics

Geometry

dx = 2 cm.

Given
Cylinder diameter D = 1 cm,
Cylinder height H = 4 cm,
Permanent magnet relative permeability μ = 1.05,
Permanent magnet coercive force H_c = 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.
