Solenoid under current load

This is an example of the solenoid under current load simulation, performed with QuickField software.

Problem Type:
Axisymmetric multiphysics problem of DC magnetics coupled to Stress analysis.

Solenoid under current load Calculate the mechanical stress distribution in the solenoid coil carrying current Winding R1 R2

Inner radius R1 = 5 mm;
Outer radius R2 = 10 mm;
Current density j = 4·106 A/m²;
Coil Young modulus E = 1.075·1011 N/m²;
Coil Poisson ratio ν = 0.33.

Calculate the mechanical stress distribution.
