Several different approaches to optimizing a ten-turn axisymmetric coil are presented.
First, the current in each turn is adjusted with the objective of having a uniform magnetic flux density along the centerline. Second, the currents are adjusted to minimize power dissipation with a constraint on field minimum at a point. Third, the currents are adjusted to minimize the gradient in the magnetic flux density along the centerline, along with a constraint on the field value. Finally, the positions of the coils, and the current, are adjusted to achieve a specified magnetic flux density at the centerline.
These models showcase shape and parameter optimization for magnetic field modeling.
You can find a detailed description of these models in the blog post "3 Ways to Optimize the Current in Electromagnetic Coils".
This model example illustrates applications of this type that would nominally be built using the following products:AC/DC Module Optimization Module
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Specification Chart and make use of a free evaluation license.
