Notes on Faraday's Lectures and Understanding Physics are currently under revision
Faraday turns his attention to forces or actions that are not based on chemical affinity directly.
- Static electricity can be generated by friction (like that between wool and glass) or contact with a charged substance.
- Electricity can be transferred by current through wires, or discharged by a ground contact.
- Lodestone possesses a new force, magnetism, that can be transferred by rubbing an appropriate substance with an existing magnet.
- Faraday demonstrates ways to generate, capture, and store electrical charge.
- Metals like copper can transmit heat energy rapidly; other materials like wood transmit heat poorly.
- Metals like copper transmit electric charge far more rapidly than they transmit heat...so heat and electricity are not the same thing.
- One can detonate gunpowder with electrical current, showing that chemical affinity and electricity are related and perhaps different forms of the same force.
