An electromagnetic field solver is a tool used to help people understand how electricity and magnetism interact with each other. Imagine you have a bunch of tiny toy cars, and you want to know how they will move when you push them around with magnets. An electromagnetic field solver helps you figure that out, but instead of toy cars, it's looking at tiny particles called electrons and protons that make up electricity.
The solver uses complex calculations and fancy algorithms to predict how the particles in electricity will move when they are near magnets or other electric charges. It can tell you where the particles will go, how fast they will move, and what direction they will take. This information is very important to people who design things like electric motors, generators, and other devices that use electricity and magnetism.
Just like playing with toy cars and magnets, the electromagnetic field solver lets you see exactly what will happen when you mix electric charges and magnets together. It's like having a magic crystal ball that can predict the future of electricity!
