rectangular spiral coil

Please login with a confirmed email address before reporting spam

Hi
I have modelled circular spiral coils placed at a distance in Z direction in 2-D and i calculated Mutual inductance by taking the help of MI and induced currents in a coil group application.Now i want to do for rectangular(or square) spiral coils.I have modelled circular spiral coils by taking 2-D axisymmetric and representing each turn by circle.I am not getting how to model rectangular(or square) spiral coils in 2-D.
I am new to comsol. i am thankful to someone who clarify my problem

Rectangular spiral coils cannot be modeled in 2D. This is a 3D problem.

Thank you sir for your valuable suggestion.
Still now i am thinking Rectangular spiral coils can be modelled in 2-D.Now i will try for 3-D.

by taking 2-D axisymmetric


I agree with the first reply. Seems like a 3D problem. About what axis of rotation do you think your square coil and associated fields are symmetric?

about Z axis coils are symmetric and placed at a distance apart

Hi,

You might find the following Application Gallery collection of 3D Coils in COMSOL useful here.

For a 2D surface coils in 3D geometry, the following example might be helpful.
