Could anybody help me out with my problem in ansys magnetic analysis??, Iam trying to do a 3-D magnetic analysis in ansys-10, I have a permenant magnet (a block) on the floor with the N-pole and S-pole along the x axis (x-y plane is the floor), then I have a piece of iron (cylindrical shape) fixed at a height ( in the z direction) to the roof (the magnet is on the floor and the piece of iron is on the roof with a small air gap in between them), please tell me how to simulate the magnetic problem and how to get the magnetic flux density on the iron piece
I have given relative permeability to the iron peice and the air gap, I have also give magnetic coercive force and relative permeability to the magnet, but some how the flux lines don't reach the iron piece or even the air gap, Iam not sure to what extent the air gap has to be modelled, or what shud be the geometry of the air gap that is to be modelled, kindly help me out, kindly giv ur advices, kindly suggest something
