Problem Type
Axisymmetric problem of DC magnetics.
Number of turns w = 400;
Applied current in wire I = 2 A;
The B-H curve for the steel core:
1. Obtain the magnetic field in coil and air.
2. Get chart Flux Density along the rotational axis of the coil
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.
