Study Notes

Conductivity

The ability of a substance to allow heat or electricity to flow through it.
Examples of good conductors include metals like copper and aluminum.
Examples of poor conductors include wood, plastic, and rubber.

Magnetism

Attraction or repulsion between magnetic objects.
Magnets have two poles - north and south.
Like poles repel each other, while opposite poles attract.

Ductile

The ability of a material to be stretched into a wire.
This property is essential for creating wires for electrical circuits.
Examples of ductile materials include copper, silver, and gold.
