Coil with ferromagnetic core
QuickField simulation example
DC current is applied to the electric coil with ferromagnetic core.
Problem Type
Axisymmetric problem of DC magnetics.
Geometry
Given
Relative permeability of the air and winding μ = 1;
Number of turns w = 400;
Applied current in wire I = 2 A;
The B-H curve for the steel core:
Task
1. Obtain the magnetic field in coil and air.
2. Get chart Flux Density along the rotational axis of the coil
Solution
Define a spherical region solution. Radius of R = 2000 mm.
In the block core values put the B-H. In the block coil enter the total coil current 800 A.
For point 2. task draw a line from the center of cores to the right end of the axis z.
Results
Magnetic field distribution:
Flux density in the core:
