Electromagnets
Quick revise
Magnets attract magnetic materials using a magnetic field
The magnetic field surrounds the magnet, and gets weaker as the distance from the magnet increases
Magnets should be called permanent magnets > the magnetism is always there
Electricity makes a magnet much stronger. This can be turned on and off
Magnets can pick up paper clips etc. Electromagnets can pick up cars e.g. scrapyards
