Solenoid Simulation

ELECTROMAGNETIC SIMULATION FOR SOLENOID DEVICES

Electromagnetism is a highly complex phenomenon which can be observed by solving Maxwell equations. These equations are governed by Gauss Law, Faraday’s laws of induction & Ampere’s law .

Electromagnetic Simulation is technique of solving Magnetic, Electric Fields & Forces acting on Solenoid devices using finite element approach.
