magnets have potential energies associated with them and whatever object they are interacting with (must have charge to interact...). this energy does work as the force is exerted on said object, the direction being dependent on the charge. so yeah magnets can pull stuff
Yes, and they can be quite powerful at doing this. The bad thing is that they can be hard to release from the item you are pulling if you can't turn them off "Permanent magnets".
I dont think you can ---- If you super-heat the magnets, it will demagnetize them, thus stopping the "pulling power" of the magnets. Basically stick the magnets in a vat of super boiling water, that should be sufficient enough heat to demagnetize the magnets.

Heck yes, with out magnets we would not have to North or South pole. If we did not have those the earth would have no magnetic pull to it. The north and South pole are like 2 giant magnets pulling all the little magnets one way so they stick on your fridge!
they actually do loose their magnetism but it takes about 20 years
Magnets can attract objects by pulling them towards each other, and repel objects by pushing them away. This is due to the magnetic field produced by the magnet interacting with the magnetic properties of the objects.
Why not? The capacity of being magnetized does not depend on the shape or on the size, but rather on the kind of material.
No, not all magnets have the same power. The strength of a magnet is determined by factors such as its size, material, and how it is magnetized. Magnets can vary in terms of their pulling force, magnetic field strength, and overall magnetic power.
The force between magnets and iron is due to magnetism. Iron is a ferromagnetic material, meaning it can be easily magnetized and attracts other magnets due to its alignment of atomic dipoles. This attraction or repulsion between iron and magnets is a result of the magnetic field surrounding the objects.
