Case 1: Cylinders are coaxial Magnetic forces between two axially magnetized cylinders. Case 1: Cylinders are coaxial. magnet attraction force, cylindrical magnet simulation Problem type: Axisymmetrical 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. Results: Case 1.
