Electromagnetism I covers the fundamental principles of electricity and magnetism. You'll dive into electric fields, Gauss's law, electric potential, capacitance, and current. The course also explores magnetic fields, Ampère's law, Faraday's law of induction, and Maxwell's equations. It's all about understanding how electric and magnetic phenomena interact and shape our world.

Is Electromagnetism I hard?

Electromagnetism I has a reputation for being challenging, and honestly, it can be. The concepts are pretty abstract, and there's a lot of math involved. But don't let that scare you off. With consistent effort and practice, most students find it manageable. The key is to stay on top of the material and not fall behind, because things build on each other quickly.
