Magnetic forces between two axially magnetized cylinders. Case 1: Cylinders are coaxial.
QuickField simulation example
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 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.
