What Makes Magnets Attract

A magnet is an object that has a magnetic field. It can be in the form of a permanent magnet or an electromagnet. Permanent magnets do not rely upon outside influences to generate their field. They occur naturally in some rocks, but can also be manufactured. Electromagnets rely upon electric current to generate a magnetic field - when the current increases, so does the field.
Magnets are attracted to, or repelled by, other materials. A material that is strongly attracted to a magnet is said to have a high permeability. Examples of materials with very high permeability include iron and steel. Liquid oxygen is an example of something with a low permeability, and it is only weakly attracted to a magnetic field. Water has such a low permeability that it is actually slightly repelled by magnetic fields. Everything has a measurable permeability: people, gases, and even the vacuum of outer space.
The SI unit of magnetic field strength is the tesla, and the SI unit of total magnetic flux is the weber. 1 weber = 1 tesla flowing through 1 square meter, and is a very large amount of magnetic flux.

Magnets attract because of the magnetic force coming from the North and South pole. That is why the needle for a compose will always point North, because of the magnetic pull.

magnetism- a class of physical phenomena that include the attraction for iron observed in lodestone and a magnet , are inseparably associated with moving electricity, are exhibited by both magnets and electric currents, and are characterized by fields of force

electromagnetic fields that are present around the magents. each side of a magnet has a "pole". just like the earth does. 2 positive sides detract from one another becuase their electromagnetism is the same , however, a positive and a negative attract becuase they are unequal. hope this helps

each magnet has a positive and negitive pole. opposites attract and so the magnets are atrracted to each other by the corresponding pole

It is due to the opposite attractions of north and south pole.

youll hate me for this but ill "bring you closer" to the answer. the earth core is magnetic because its molten nickel&iron moving around, right? and protons and electrons are attracted to each other, right? and wikipedia does exist ,right? just wikipedia it for petes sake!

trublood is right, if you go to another planet or the moon it will change
