The transfer of energy between two objects at different average thermal kinetic energies (temperatures) is referred to as heat transfer. It is always called heat transfer, regardless of what kind of energy is being transferred.
This would be called a photocell.
Domains are aligned.
temporary magnets

a magnet always has two poles
The term used to indicated wet cell batteries is electrolytes. Electrolytes indicates that there is a charged solution contained in wet cell batteries.
The device is called a "variac' and it is a type of transformer. It has a variable voltage ouput.
It can easily be transformed up to a high voltage for power transmission, and back down for home supplies at 120/240 volts.
All life on earth is interdependent.
