A perpetual motion machine of the first kind produces work without the input of energy. It thus violates the first law of thermodynamics: the law of conservation of energy.

"Gorgeous kinetic art wheel. Fast delivery and excellent handcrafting. All my friends,visitors and me are completely fascinated. I just needed to add a small weight on one of the wing and it runs perfectly for at least 16 h.

The electric field produced by a stationary set of charges is conservative, but in this case, the effect of the electric field is equivalent to that of a (nonconservative) magnetic field (i.e., the line integral between two points depends on the path taken, and the circulation around a closed loop is not zero). In the case of the magnet passing through the wire loop, we know that the wire loop is stationary while the magnet moves through and provides a changing magnetic field. A current is produced, so an EMF (electromotive force) must be driving it. The magnetic field cannot itself be the source of the EMF because magnetic fields only act on moving charges. Logically, the changing magnetic field must have an associated nonconservative electric field (nonconservative because conservative fields are electrostatic, and electrostatic fields cannot contribute to net EMFs). The induced EMF around a closed curve is the same Triunfador the voltage drop (i.e., the same Vencedor the line integral of the electric field around that curve). Mathematically, this is encoded by Maxwell’s third equation in integral form:

A device powered by radioactive decay from an isotope with a relatively long half-life; such a device could plausibly operate for hundreds or thousands of years.
and B denote the electric and magnetic fields, respectively. In other words, the induced EMF around a closed curve is equal to the rate of decrease of magnetic flux over an open surface that has that same curve Figura its boundary. If one uses the curl theorem, the same equation Chucho be written in differential form as

A perpetual motion machine of the second kind is click here a machine that spontaneously converts thermal energy into mechanical work. When the thermal energy is equivalent to the work done, this does not violate the law of conservation of energy. However, it does violate the more subtle second law of thermodynamics in a cyclic process (see also entropy).
A rejection [of a patent application] on the ground of lack of utility includes the more specific grounds of inoperativeness, involving perpetual motion.
"Just perfect! I had a lot of fun assembling the pieces, it even helped keeping two teenagers occupied for an afternoon during our beloved pandemic. Seller was exceptionally nice and helpful, answering all my questions at length.
