Resonance 7 – Electromagnetism and Light

Resonance 7 covers the 7th module of high school physics (Electromagnetism and Light). The module focuses on electromagnetism as a field where electric and magnetic interactions occur side by side. The course covers time-dependent electromagnetic phenomena, with electromagnetic induction being the most central. It also explores electromagnetic radiation, especially its most familiar form – light. When examining applications based on electromagnetism, the focus is on their role in enabling the development of society.

The learning material is made in accordance with the Finnish upper secondary school curriculum (LOPS2021).
