Magnetic materials: Iron, steel, cobalt, nickel (and their alloys)
Permanent magnets:
- Produce their own magnetic field constantly
- Made from "hard" magnetic materials like steel
- Always have both a NORTH and SOUTH pole
Induced magnets:
- Become magnetic when placed in a magnetic field
- Made from "soft" magnetic materials like iron
- Lose magnetism when removed from field
- Always ATTRACTED to permanent magnets (never repelled)
Poles:
- Like poles REPEL (N-N or S-S)
- Unlike poles ATTRACT (N-S)
- You cannot isolate a single pole — cut a magnet and you get two smaller magnets!
