the force between the earth and moon, the force between the sun and the earth, the force between the two magnets, the force between iron material and magnet.
well of course magnets!m we get it from the magnetic pole as well!

Who the hell cares..
Yes some energy is lost in each energy transfer reaction ,it is due to second law of thermodynamics .no energy transfer can be 100% efficient .

Kinetic energy is defined in terms of motion, so anything in motion is exhibiting kinetic energy.
tidal energy is used to turn turbines which drive generators to produce electricity
There are three means of heat transfer, Convection, conduction, and radiation. All three occur to some degree in all heat transfer processes.

Energy in the form of electro magnetic waves. Some examples are light,heat,UV etc
A magnet
Many of the energy conversions that go on in a cell involve reactions in which an electron is transferred from one substance to another. This is because the transfer of an electron also involves the transfer of the energy of that electron. Such an electron transfer is called a redox reaction. Examples are photosynthesis and cellular respiration
Magnetic energy is now being used to power some homes.
It takes some energy to build up a magnetic field; when the magnetic field collapses, the same amount energy is released again. So, it makes sense to consider that somehow, energy is stored in the magnetic field.
Some examples of dynamic units are magnetic disks, magnetic drums, and magnetic tapes
