All magnets are entirely surrounded by their magnetic field
|
Magnetic force is strongest at the poles
|

Copper objects will therefore not be attracted to a magnet
|
Maglev (stands for magnetic levitation) trains use this idea to lift them off the ground
|

Opposite poles attract, similar poles repel
|
It lines up with the magnetic field of the Earth
|

A compass points to magnetic north and not geographical north, so, when using a compass for navigation, the difference in location between the two poles has to be taken into consideration
|
The other materials are not affected by a magnetic field

Steel contains mainly the element iron

Magnetic force acts at a distance
