know that magnets repel and attract other magnets and attract magnetic substances
describe the properties of magnetically hard and soft materials
understand the term magnetic field line
know that magnetism is induced in some materials when they are placed in a magnetic field
practical: investigate the magnetic field pattern for a permanent bar magnet and between two bar magnets
describe how to use two permanent magnets to produce a uniform magnetic field pattern
