Reflect and research
- When was magnetism first discovered?
- What is the origin of the word “magnetism”?
- What experiments support that magnetic monopoles do not exist?
- What did J.J. Thomson measure, and how?
- How do debit and credit cards use magnetism?
To try at home
- Attempt to construct a compass using household materials.
To try in the lab
- Propose an experiment to measure the magnitude of Earth’s magnetic field.
- Propose an experiment to construct a galvanometer and test its accuracy.
