Philip H. Diehl was a German-American mechanical engineer and inventor who held several U.S. patents, including electric incandescent lamps, electric motors for sewing machines and other uses, and ceiling fans.
No, a fan is not a living thing. It is a mechanical device designed to create airflow and cool spaces by moving air. Living things possess characteristics such as growth, reproduction, and response to stimuli, which a fan does not exhibit.
A fan uses magnets by generating a magnetic field that interacts with electric current, which creates a force that drives the fan blades to rotate. This rotation creates airflow, providing cooling or ventilation in various applications. Magnets play a crucial role in converting electrical energy into mechanical energy in a fan.
Your mechanical valve is made of surgical steel. Magnets are attracted to steel.
The first "machine" was the Wheel
the first mechanical clock was made in 723 A.D. by a buddhist monk named Yi xiang
An electric fan is not "an mechanical energy". An electric fan converts electrical energy into mechanical energy (the movement of the fan blades, and hence, the movement of the air).

First changes into magnetic energy that leads to mechanical energy along with some heat energy
When the first humans made ​​their first tools.
Schulyer Wheeler invented the electric fan in 1886.
-- radio transmitter = electrical energy into electromagnetic energy -- microwave oven = heat energy -- electric motor = mechanical -- toaster = heat -- light bulb = heat and light -- battery charger = chemical -- blow drier = mechanical -- coffee percolator = mechanical -- electric fan= mechanical -- flashlight = light -- electric kitchen mixer = mechanical
