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.
they actually do loose their magnetism but it takes about 20 years
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.
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".

Magnetic
Both
REPEL
because it is bigger than the little magnets and has more power than the little magnets do.
yes the giant drop stops by 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!
With magnets
By rubbing two magnets together.
