Presentation Transcript
Magnet a rock or a piece of metal that can pull certain types of metal toward itself.
Attract to pull to or draw toward itself
Iron Iron is a metal and the sixth most common chemical element in the universe
Cobalt Cobalt is a transition metal, which is an element that is shinier, harder, and less reactive than other metals
Force A force is a push or a pull.
Repel to push away
Steel Steel is iron mixed with carbon and perhaps other metals.
Nickel a hard silvery white metallic chemical element
Magnetic force attraction or repulsion that arises between electrically charged particles because of their motion.
Magnetic materials materials that can be either attracted or repelled when placed in an external magnetic field and can be magnetised themselves
Attracted magnetic field The magnetic field is the area around a magnet that has magnetic force
Non-magnetic materials materials which are not attracted by a magnet are called non- magnetic materials
Magnetic poles the region at each end of a magnet where the external magnetic field is strongest.
Materials A material is any substance that has a name.
Invisible unable to be seen
North North is one of the four compass points or cardinal directions.
metal A metal is a material that, when freshly prepared, polished, or fractured, shows a lustrous appearance, and conducts electricity and heat relatively well.
South South is one of the cardinal directions or compass points
