How the B-H Curve Affects a Magnetic Analysis (and How to Improve It)
Magnetic soft iron steels are widely used as core materials in motors, transformers, and inductors. The B-H curve is used to describe the magnetization properties of such materials.
10 Real Uses of COMSOL Multiphysics® in the Power Industry
Minimizing transformer noise, planning underground cable networks, and managing a power grid. Keep reading for more real-world examples in which simulation is used in the power industry.
Samsung Amps Up Loudspeaker Designs with Simulation
Some organizations reach success and then shift the goal post. Take Samsung, for instance: Although they lead the market for televisions and smartphones, they set their eyes on another goal…
Building a Magnetohydrodynamic Multiphysics Model in COMSOL®
Magnetohydrodynamic models call for fluid dynamics and electromagnetics couplings. To do so, you can set up bidirectional couplings between all physics equations or building a simplified model.
Speeding Up DNA Separation in a Microchannel via Simulation
DNA separation takes a long time using traditional methods. Now, researchers from the Missouri University of Science and Technology have found a faster way to get the job done.
Reducing the Magnetic Signature of a Submarine
For a submarine to avoid detection and remain “under the radar”, engineers need to investigate the magnetic signature of the vessel’s design. Electromagnetics simulation is up to the task.
How Eddy Current Braking Technology Is Freeing Us from Friction
What moves must eventually stop. Unlike mechanical brakes, eddy current braking systems prevent damage when braking at high speeds. Hop on and learn more about eddy currents in this blog post.
Designing Heating Circuits with Multiphysics Simulation
The electronic message boards you see on the highway contain heating circuits. Their design is a truly multiphysics problem involving heat transfer, structural mechanics, and electromagnetics.
