How to Model a Hall Effect Sensor with COMSOL Multiphysics®

March 11, 2021

Basic working principle of a Hall effect sensor: A nearby magnetic field deflects the path of current through a semiconductive sensor, which causes a measurable change in potential.

Which Radiation Interface Should I Use for My Heat Transfer Model?

March 4, 2021

Compared to the mechanisms of heat transfer by conduction and convection, heat transfer by radiation has unique characteristics. How should you account for radiation in your heat transfer models?

A Quiet Revolution: Analyzing Electric Motor Noise via Simulation

March 2, 2021

The sound we hear from electric-powered machines is a multiphysics phenomenon: A motor’s electromagnetic activity sends vibrations through both the machine and the surrounding air.
