Becomes a magnet near a magnet, then loses its magnetism when moved away. Temporary magnet
Anything that attracts or repels another magnet or magnetic material. Magnet
The North Pole; where maps point to as north. True north

Two magnetic north or south poles: Repel
A magnetic north and south pole: Attract
3 ways to increase an electromagnet 1) Use a stronger battery 2) Increase and tighten the coils 3) Add more iron to the core
How do you draw a magnetic field - drawn from North pole to South pole; - closer or more arrows = stronger field.
