Magnetic forces between two axially magnetized cylinders. Case 3: Cylinder axes are orthogonal.

Problem type:
Axisymmetrical problem of DC magnetics

Geometry:

two axially magnetized cylinders model

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 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.

Results:

Case 3: Cylinder axes are orthogonal.	F_x	F_y	F_z
Cylinder PM force 3D tool	5e-16 N	-1.18 N	-0.14 N
Reference (ANSYS 3D)	0.07 N	-1.17 N	-0.08 N
