TOPMAG’s industry-leading engineering team is at the heart of the outstanding value that we provide to our customers. We have extensive expertise in all aspects of the design and testing of permanent magnet and electromagnet components, assemblies and systems. Engineers from a variety of fields support in magnetic material selection, magnet evaluation, assembly design and program management.

Multi-disciplinary in nature, our team has engineers with masters and doctorate-level degrees in electrical and mechanical engineering, physics and materials science. Our team holds multiple patents for innovative magnetic technologies, with numerous patents currently pending.

In short, we know magnetics. This allows us to bring the right technical resources to bear on even the most challenging of engineering designs. Our design engineers work closely with our process and manufacturing engineers at all stages of the design cycle, ensuring cost-effective manufacturability and advanced planning of fixtures, tooling and other supporting components.


The engineering team at TOPMAG uses a variety of software tools to effectively model, design and produce magnetic components and assemblies. Initial design concepts are further developed using SolidWorks, the industry’s leading 3D solid modeling software tool. With this software we can produce complex parts and assemblies and associated drawings very efficiently.

SolidWorks integrates well with Lorentz, our primary 3D magnetic modeling software that can be used in either finite or boundary element analysis [FEA / BEA] mode to produce modeled results. Our engineers can use Lorentz in parametric mode, to automatically run multiple iterations of magnetic models efficiently. Optimized model designs can then be imported into Solidworks for the creation of engineering drawings.



Our engineers also use Ansys, a powerful multi-physics FEA modeling tool, as well as Magneto, a 2D / rotational symmetric magnetostatic modeling tool and Oersted, for modeling losses due to eddy currents.  We also use a variety of other, proprietary software tools to aid in our design process.

Underlying the use of all of our tools is a solid, fundamental understanding of magnetostatics and general magnetic circuit design and analysis.

An essential part of testing, verification, and troubleshooting of a magnetic device is field mapping.  Our magnetic field mapping devices are completely automated, but can be manually controlled if an application requires.  For most applications, an automated solution is most efficient and convenient.  The mapper is given the required mapping space in all three dimensions, specifies a resolution, and lets the mapper collect data with its three-axis probe.  The mapping device then exports the magnetic field data to file once acquisition is complete.  We can process the data in-house as needed, or the raw data can be delivered directly to the customer for analysis in the customer’s favorite data processing software.
