Why would a peretual machine never work?

Because magnets wear out. Magnetic perpetual machines can never work because magnets eventually wear out. This isn't the reason they don't work. Magnets can lose their magnetism in several ways; Heat them to very high temperatures. Hit them repeatedly with a hammer.

It'd never work as the first law of physics is that the law of conservation of energy. It states that energy is often preserved. To keep a machine moving, the energy applied ought to stay with the machine with none losses. As a result of this reality alone, it's not possible to make perpetual motion machines.

Hope it helps!<3

when atmosphere interacts with biosphere they focuses on on the sources and sinks of green house gases (ghgs) air pollutants, particular matters, water and energy between the earth's surface and the atmosphere. the biosphere affects the climate. the atmosphere and biosphere are in constant interaction with each other, and all living things rely on gases in the atmosphere for life. organisms such as animals take in oxygen gas form the atmosphere to use in every cell of their body for smooth functioning of daily routine exercises.
