1) Click on the link below, and read the passage about the history of electromagnets.
---1a: Explain/describe what James Maxwell observed when he caused electric current to pass through a wire.
---1b) Explain/describe what Hans Christrian Oersted observed with a compass and a battery.
2) Click on the link below, and read the passage about how electromagnets work.
---2a: What are the two basic components found in electromagnets?
---2b: What happens to the metal core (typically iron) when electric current (electricity) flows through the coiled wire (solenoid) in an electromagnet?
---2c: Explain/describe the difference(s) between a permanent magnet and an electromagnet (contrast them).
3) Click on the link below, and read the about the "sticking" power of magnets.
---3a: When constructing an electromagnet, what could you do to make it produce a stronger magnetic field?
---3b: Explain/define this term: ferromagnetic metal
---3c: Explain/define this term: magnetic permeability
