I wish to design 2D planar coil to calculate the magnetic flux density. From tutorials, I designed the planar coil geometry, along with added magnetic field (mf) physics and stationary study.
The issue is,
1) the designed coil circuit is not closed but when I give external current density (current / surface area of the coil) under mf study, the flux density generated is decreasing with increase in number of turns, i.e., against theoretical formulas.
is't correct using current density option in mf mode for coil geometry?
input direction (j_e): x= j*(-y/sqrt(x^2+y^2)) [A/m^2]
y= j*(x/sqrt(x^2+y^2)) [A/m^2]:
z=0 [A/m^2]:
pl. correct me.
2) I read in COMSOL form that the Closed Current Paths is important to design coil geometry (www.comsol.com/blogs/modeling-coils-in-the-acdc-module/). This could be made by a bridge between the two edges.
but,
may I know, how to use current flow to the closed coil geometry with proper guidance.
Thanks.
