-It can be learned through an experiment. Planet Earth itself is a giant dipole magnet; N to N or S to S= repulsive force; S to N = attractive force.
if you break a magnet down to one last individual atom, you still have a dipole field because of the atomic-scale current loop. If you try to break the atom down further, the dipole field will disappear and there will be no magnetism except that associated with the particles themselves. Thus magnetism in nature is ultimately related to the arrangement of electrical charges rather than to anything intrinsic to matter itself.

Do bar magnets have south and north poles?
Yes. All magnets of north and south poles. There is no such thing as a magnetic monopole.
Do bar magnets have a north and South pole?
Yes. All magnets of north and south poles. There is no such thing as a magnetic monopole.
Bar magnets display a characteristic type of charge called?
Dipole Field
How do you get a single south pole of a magnet?
You don't. Magnets ALWAYS have two poles, or "dipole". Cut a magnet in half, and it will still have two oppositely charged poles (ie: north/south; pos/neg; etc). What you seek is called a "monopole" & unfortunately, science had yet to figure out how exactly how to create/produce monopoles - or at least one that can be successfully utilized for laboratory testing purposes, and a far cry for any applicable uses. The search for the "Monopole" is the science of Electromagnetism's holy grail.
What is the difference between monopole antenna and dipole antenna?
Monopole is an antenna with just the radiating element where the ground of the transmitter is connected to an electrical ground which serves as an Image ground to the radiating element. Thus the name "mono" pole. Dipole is where the ground and the radiating elements are connected to two different elements where one is the radiating element and the other is the ground to the later. Thus the name "Di" Pole Cheers by zafran khan
Do different magnets have different magnetic fields?
yes
Do any other plants besides the earth have magnets in it?
Yes. They don't have actual magnets, but they do have "magnetic fields". Other planets with magnetic fields are Mercury, Jupiter, Saturn, Uranus and Neptune.
What do magnets have to with electricity?
Faraday showed that a wire passing through a magnetic field will produce electricity. This is how a generator works. Many windings of wire on an armature spin in a magnetic field. This makes electricity.
Why some materials are magnets and some are not magnet?
Ferro magnetic materials (those attracted to magnets) have a special arrangement of their electrons which makes them susceptible to magnetic fields. Materials without this special electron structure are not affected my magnets or electric fields in the same way.

When the magnetc fields of two or more magnets overlap what is the result?
It sticks
Do scientists talk about invisible magnetic fields around magnets?
Yes.
