hi /sci/,

I didnt find the answer in a quick 5 minutes-google research so I'm asking you: are there motors made of magnets which acutally work and produce energy? If the answer is no, I'd like a explanation, if it's yes, tell me why they are not common(inb4 conspiracy)

its called a generator

I'm talking about engines producing energy JUST from magnets.

Considering op didn't say that the motor needed to output more energy than it draws to operate....yes generators, and power plants.

there isn't such a thing, otherwise it's a perpetual motion machine. there's always another gimmick, such as gravity or heat difference. and there are always losses, even with magnets. so you can't really call it a motor

The magnets would have to carry charge. The magnets by themselves aren't giving off current.

Magnetic fields do no work.

>highschool fag thinking there's such thing as free energy
