No, some are more powerful than others, as there are your normal refrigerator magnets that hold a few sheets of paper and there are super electromagnets that can hold cars.
Nothing, elctro magnets act just the same as permanent magnets
No. The same two magnets can either repel each other or attract each other, depending on how you turn them. The force is the same either way.
Yes, they repel when the same poles are together.
Well, yes, kind of. But they are not magnets, it's gravity.
In business factors that are all the same are called a pyruvate. A pyruvate are microorganisms of the same product that are produced.
Different magnets have different powers some may be small and have a strong power and some may be big and have a weak force. So the answer to that question is no.
You can power a fan by putting magnets on all the flaps that make the air then put another magnet near it to make it move and the repel of the magnets will create movement.
Cold. If magnets get overheated, they can cease to work all-together.
The answer depends on whether the five magnets are all the same! But assuming they are, the answer is yes.
There are many different types of power plant but they all produce electricity the same way: by spinning huge magnets around an iron core inside a device called a turbine.
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.
because it is bigger than the little magnets and has more power than the little magnets do.
Magnets are able to attract magnetic objects.

With magnets
By rubbing two magnets together.
A bullet train gets it's power from extremely powerful magnets. The magnets are on the sides of the track, and train.
