I was messing with magnets today, and I was wondering if we could do this. We could use positive against positive or negative against negative to push things somehow, and positive and negative to pull. Did someone else already invent this? I really think that these magnets can have a huge effect on society and our industry if we discovered how to use them.
This is random, but for the girls that don’t have their ears pierced can use magnet earrings. (Earrings that have magnets that come together).
What do you think?

We understand magnetism perfectly well. Here’s the flaw in your reasoning:
Whatever energy you gain in bringing two magnets close together, you lose in moving them further apart. In fact, you can’t even get back as much energy as you put in, because some will inevitably be turned into heat, and will escape.
There is no possible combination or orientation of magnets that will give you a continuous supply of energy. It is physically impossible – a direct violation of known physical laws.
However, magnets do have their uses. If you have an exterior source of energy (say, a dam, which is powered by water pressure from a reservoir which is filled by water evaporated by the Sun), then magnets (in a generator) can be used to convert that energy into electricity.
Ha i always thought the same thing,i thought about putting them on the blades of a windmill,just think about it as one blade with a pos is pulled toward another as the force passes it is propelled by the neg. etc etc etc??
The attractive and repulsive forces of magnets are used in virtually every electric motor and generator. This is the most common way to change mechanical work into electrical energy and vice versa.
