Magnetic forces and Magnetic Poles
What is magnetic force?
Magnetic force/magnetism is the the force that magnets exert on materials that contain iron, steel, cobalt and nickel.
What are magnetic materials?
Magnetic materials are objects that are attracted by a magnet.
What are nonmagnetic materials?
Nonmagnetic materials are materials that are not attracted by a magnet.
What is the north pole?
The north pole is a pole at the end of a magnet that is dissimilar to the south pole.
What is the south pole?
The south pole is a pole at the end of a magnet that is dissimilar to the north pole.
What is polarity?
Polarity is when a molecule has a slightly positive end and a slightly negative end.
Magnets have a definite polarity.
List two characteristics of magnetic force.
>Magnetic force is attractive or
repulsive
> Magnetic force acts over a
distance.
