Magnetism.
A magnet pulls objects towards it or pushes objects away from it.
When a magnet pulls something, it attracts it.
When a magnet pushes something away from it, it repels it.
Magnets can move, pull or push magnetic objects without touching them. This invisible force is called magnetism.
Identify Poles of a Magnetic.
When you place iron fillings on a sheet of paper and place a magnet bar on the sheet of paper, you will observe that the iron fillings are attracted more towards the region close to the two ends of the magnet bars.
Poles of a magnet are said to be near the end of the magnet bars.
All magnets have two ends that are called magnetic poles.
These are North pole and South pole.
Most magnets are labelled N and S where N stands for North pole while S stands for south pole.
The magnetic force of a magnet is strongest at the poles. This means that the poles attract and repel more than the other parts of the magnet.
