Can a Perpetual Current Machine Actually Exist?

In summary, using a magnet to oscillate in and out of a coil of wire may generate an electric current, but it would not produce a perpetual source of power. The physical force needed to create the current would eventually slow down the oscillation of the magnet and it would come to rest. This applies even with the use of larger magnets to repel the magnet. The inductance of the coil may also play a role, but the magnet will eventually stop moving.

If a magnet could somehow oscillate in and out of a coil of wire and used to power a light bulb, could that power the light bulb forever?

I learned in class that running through a magnet through a coil of wire could produce an electric current. If we had two magnets powerful enough to repel the magnet from side to side, could that create a perpetual electric current?

Sorry if my question is stupid.

Its ok.

It takes physical force to create that current, so the act of creating the current would slow the oscillation of the magnet.

russ_watters is right. The magnet will be repelled to and fro between the two larger magnets, sure.. But the oscillations will slowly die and and the magnet will eventually come to rest in a position where the two repelling forces are equal. Ofcourse, there is the inductance of the coil involved too which might support or go against the motion of the magnet. But the essentials remain the same. The magnet will stop.
 

What is a Perpetual Current Machine?

A Perpetual Current Machine, also known as a perpetual motion machine, is a hypothetical machine that can continue to operate without any external energy input.

Is it possible to create a Perpetual Current Machine?

No, according to the laws of physics, it is not possible to create a Perpetual Current Machine because it would violate the law of conservation of energy.

Why do people still research and talk about Perpetual Current Machines?

Although it is not possible to create a Perpetual Current Machine, the concept has captured the imagination of scientists and inventors for centuries. Many people still research and talk about it as a thought experiment and to explore new ideas and technologies.

What are some examples of Perpetual Current Machines?

Some common examples of Perpetual Current Machines include the water wheel, pendulum clock, and windmill. These machines use natural forces, such as gravity and wind, to continue their motion without any external energy input.

What are the potential applications of a Perpetual Current Machine?

In theory, a Perpetual Current Machine could have endless energy, which could have numerous applications in various industries. However, since it is not possible to create one, there are no practical applications for it currently.
