A coil is a basic building block of any electromagnetic device such as transformer, motor, relay, solenoid or electromagnet. Detailed knowledge of all the available coil modelling features will equip you to confidently perform any electromagnetic simulation.
This course is extensively about modelling coils in COMSOL Multiphysics. You will learn the use of the geometry part library and modelling all variants of single conductor and homogenized multiturn coils. You will learn how to use Infinite Element Domains to reduce the size of air domain surrounding your electromagnetic device. In the final tutorial, you will learn Frequency Response Analysis (FRA) of a coil to extract the impedance of the coil as a function of the excitation frequency.
