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

magnetic forces, magnetic attraction and repelling, , magnetized cylinder interaction

Problem type:
Axisymmetric 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.

Results:
