Potential Of Metals
The model demonstrates the basic effects of electromagnetism - the potential of various metals. It presents a static device for showing the principle of galvanic cells.
Wooden circular desk with various metallic materials hand-shaped forms and the built-in display showing electricity in uA.
Touch samples of various metallic materials (Titanium, Ferrum, Aluminium, Stannum, Copper) with both of your hands and close the electrical circuit. Watch how your own body works as an electrolyte. The final electricity rate can be seen on a light scale.
