Is there such a thing in existence as an engine or generator that runs on nothing but magnets. I’m not talking about electromagnets ,because that still uses electricity, but a motor that uses no fuel source other than the natural energy from magnets.

Magnets provide a force not energy. They can only be used to help implement other systems that transform energy, such as motors and generators. You should see them as more like a lever.
To make use of magnets to transform energy you have to be able to turn them on and off, which is why electromagnets are needed.
The laws of thermodynamics explain why the idea or free energy and perpetual motion machines is not possible, though the connection may not be obvious to a casual reader. Basically you can only transform energy from one form to another, and this occurs with losses always, always moving towards the zero energy state. You can’t get something for nothing because energy cannot be created or destroyed.
