Reflect and research
- Who first discovered induction? Why is it called Faraday’s Law?
- Give a few examples of applications of magnetic braking.
- How does a microphone make use of electromagnetic induction?
- What is magnetic damping?
- How does an induction stove work?
- How does a credit card swipe reader make use of induction?
- What is the origin of Maxwell’s equations? When did he publish them?
- Who was the first to detect electromagnetic waves? How were they produced and detected?
To try at home
- Demonstrate magnetic braking by moving a conducting piece of material through a magnetic field.
To try in the lab
- Construct an AC generator.
- Propose an experiment to measure Earth’s magnetic field using induction.
- Propose an experiment to measure a bar magnet’s strength using induction.
